Chromatography Essay examples -- essays research papers

Chromatography is a separation technique in which the mixture to be separated is dissolved in a solvent and the resulting solution, often called the mobile phase, is then passed through or over another material, the stationary phase. The separation of the original mixture depends on how strongly each component is attracted to the stationary phase. Substances that are attracted strongly to the stationary phase will be retarded and not move alone with the mobile phase. Weakly attracted substances will move more rapidly with the mobile phase.   Ã‚  Ã‚  Ã‚  Ã‚  Liquid chromatography is an analytical technique that is useful for separating ions or molecules that are dissolved in a liquid phase. If the sample solution is in contact with a second solid or liquid phase, the different solutes will interact with the other phase to differing degrees due to differences in adsorption, ionic strength, polarity or size. These differences allow the mixture components to be separated from each other by using these differences to determine the transit time of the solutes through a column.   Ã‚  Ã‚  Ã‚  Ã‚  Simple liquid chromatography consists of a column with a fritted bottom that holds a stationary phase in equilibrium with a solvent. Typical stationary phases (and their interactions with solutes) are: solids (adsorption), ionic groups on a resin (ion-exchange), liquids on an inert solid support (partitioning), and porous inert particles (size exclusion). The mixtur...

Nature is our friend Essay

Time has come now to realize that the energies of the Earth’s own kingdoms are very precious! The plants own natural state of love, joy and pride, is the core essence of Life. This is the understanding we all need to free ourselves from limiting thought forms. see more:trees our best friends essay 150 words The new consciousness contains a great love both for the planet and the nature. The new thinking will make us change our attitudes to plants and animals that continuously give us gifts. Many people on Earth have taken the nature for granted. It is here as en obvious part of life, it seems, and very few of us have really noticed how many gifts we are receiving from plants and animals. Every single particle in what we eat is conscious. Everything we take into our bodies comes from nature! The development has now entered a new track. We will all soon feel the connection to nature in a new way and start giving thanks to the specific plants that we love to eat and use as a part of our life, for example cotton an linen. It is really a gift from the plants to us. As they consist of conscious particles, they receive the gratitude from us by the particles’ mutual togetherness system. The Earth is an interesting planet for beings from many dimensions because it is very special†¦ because we have water and we have the rich life in nature as a consequence of that. This is an enormous abundance, consisting or the light particles of our solar system. It is really time to appreciate that we live on the most precious planet in our galaxy. The journey through the suffering and separation is soon over. The next years to come, we all will open our eyes for the true gifts of nature. It will lead us to new choices. When we chose to incarnate in physical body, one of our goals is to enjoy nature because this is the only planet where we can do it. When we one day move on, our love for nature and our ability to visualize what it looks like, make us able to create trees and flowers in our gardens in higher dimensions..:) by our own thought power. We live on a planet where we originally have developed from simple beings, like Darwin discovered. However, we have not developed because the  strongest won like Darwin said. The human race is what it is because we were transformed from Neanderthals by creating masters that originally came from other civilizations in our galaxy thousands of years ago.

Karl Marx’s theory

The theory of Karl Marx as regards society and how it should move and organize itself is contrary to the view that all the members of the community must collaborate and contribute to the greater and common good. For Karl Marx, conflict is necessary in order to effectuate changes within the society. In fact, he considers conflict the most fundamental ingredient in making change possible in a given society.The foundation of this theory is Karl Marx’s theory that the society is composed of different classes. The class to which a particular person belongs will largely depend on the role or part played by that individual within the bounds of society. Where classes exist, people are continuously segregated, and hence it cannot be said that there is presence of absolute equality. Hence, for Karl Marx, this is where conflict begins.His belief in the formation of classes is traced in his notion that men has been in constant contrast with nature or his environment. There is the belief t hat due to man’s active participation or connection with his environment, he finds more and more ways to contrast with it in order for him to survive. As correctly pointed out,Marx insisted that men make their own history. Human history is the process through which men change themselves even as they pit themselves against nature to dominate it. In the course of their history men increasingly transform nature to make it better serve their own purposes. And, in the process of transforming nature, they transform themselves.In contrast to all animals who can only passively adjust to nature's requirements by finding a niche in the ecological order that allows them to subsist and develop, man is active in relation to his surroundings. He fashions tools with which to transform his natural habitat (â€Å"Dynamics Of Social Change†).Hence, men found it imperative to formulate measures and processes in order for him to survive. This is the same need that moved and provoked men t o associate with other individuals that are more like them. This is the start of the formation of classes where men of the same roles in the society grouped and formed their own class for purposes of survival.Due to the creation of different classes or groups within the society with the same purpose, said groups found themselves in conflict with one another. This is due to the fact that for purposes of subsistence, one class must necessarily dominate all the other classes in the society. In a scenario where different classes exist with one purpose, the presence of conflict, for Karl Marx, is inevitable. â€Å"Classes are conflict groups involved in extremely intense and violent conflicts directed toward equally extremely sudden and radical changes†(Dahrendorf, 1959). Due to their struggle to survival, it becomes imperative that the classes be in conflict with one another. The subjective class deemed it necessary to rise above the dominating class.In order for the subjective c lass to rise above the dominating class, it becomes crucial for conflict to exist. As mentioned above, it was the view of Marx that men as beings do not merely adapt to his nature. In order to survive, men find means and process to fight back and struggle with nature. This is precisely what happens in the society, the people do not merely assent to what constantly occurs within the society, and hence conflict must be created for change to materialize. Marx believed that if the lower class simply cooperated with the higher class, exploitation will continue and worsen until change is no longer possible.For Marx, society cannot change nor move forward if people simply assented to the appeals and desires of the dominant class; that society cannot be changed if men simply adhered or responded to nature. Marx put too much premium in the concept of conflict as a tool for transforming the society people live in. Truthfully, in the world we live in today, conflict is not difficult to find. A s correctly pointed out by Dahrendorf, â€Å"we can maintain at the very least that in many societies there are associations and classes, and in all known societies social conflicts†(1959). And within each society, conflict is not a simple element, but rather a necessary one.   For Karl Marx, In order that change to the systems running the society and arrangements within the society to be effected, conflict, albeit a negative term, is a necessary tool which must be considered and utilized.REFERENCERalf Dahrendorf.

John Proctor in The Crucible Essay Example

John Proctor in The Crucible Essay Example John Proctor in The Crucible Paper John Proctor in The Crucible Paper Essay Topic: The Crucible Arthur Miller was born on October 1915 in New York City. His Family came from Austria and immigrated to America. The 1929 stock market crash, and the economic depression that followed it, ruined the family business so that when the young Miller graduated high school there was no money to send him away to University. So instead, he took various jobs to earn money, including two years at a shipping clerk in an automobile- parts warehouse in Manhattan. He applied to the university of Michigan in 1934 where he studied history and economics, but also taking a course in journalism and playwriting. Arthur Miller has written many successful plays in his lifetime, including All My Sons which opened in 1947 and ran 328 performances on stage. Arthur Miller was inspired to write The Crucible by reading a copy of Marion Starkeys book The Devil in Massachusetts. He believed that The Crucible had relevance to the time the play was written. He believed that the American government was on a witch-hunt to destroy communism because they were scared of the power countries in Asia and the USSR had, which is like the people in Salem, who felt they had to hang witches, because they were scared of the power witches may have. The Crucible is about the true story, of The Salem Witchcraft Trials. This began when a group of adolescent girls did some amateur dabbling in the supernatural in Massachusetts in 1692. The result of the witchcraft trials, ended up with the jails full and 20 people hanged. The inhabitants of Salem believed that the bible had instructed them that all witches should be hanged. The girls included a West Indian slave, Tituba, with her spells and beliefs. Betty Parris, the daughter of the minister, started to behave like a child possessed, lying in a trance and sometimes crawling around like an animal with her cousin, Abigail Williams. This behavior was probably what people would call psychosomatic but in seventeenth- century Salem, the only explanation was that the children were possessed by the Devil. In court the girls were in hysteria as they discovered their power in naming innocent people as accomplices of the Devil. No one could argue with their accusation because the only witnesses to witchcraft were the girls. The only way for someone accused of witchcraft to keep their life, was to make a confession. In naming people, the girls were probably projecting their own guilt on the innocent. One such innocent was Elizabeth Proctor, (John Proctors wife) who was accused by her former maid, Abigail Williams. John Proctor, the main character, called on to denounce his wife, his friends and neighbors and finally himself, he goes through an ordeal by conscience, eventually accepting his own death than make a false confession. When Miller wrote The Crucible, he portrayed John Proctor as a hardworking farmer in his middle thirties. He was even- tempered, with a mind of his own. The character John Proctor is first mentioned to the audience when he is mentioned by Betty Parris in act one, in Reverend Parriss house, when she wakes form her coma like state. Abigail Williams and the others girls are around Betty, talking, about when the groups of girls including themselves were dancing in the woods around a bonfire. Abigail tells Betty that she had told her uncle (Reverend Parris, Bettys Father) all about them dancing, but Betty reveals to the audience that Abigail did more than dance; Betty: You did, you did! You drank a charm to kill John Proctors wife! You drank a charm to kill Goody Proctor! This would give the impression to the audience that John Proctor is a popular man, and Abigail may have a crush on him. John Proctor then enters the room and Mary Warren his servant leaps in fright, this would have given an audience the impression that Proctor is quite strict and frightening. Mary: Oh! Im just going home, Mr. Proctor. John Proctors first line is Proctor: Be you foolish Mary Warren? Be you deaf? I forbid you leave the house, did I not? Why shall I pay you? I am looking for you more often than my cows! This gives the dramatic impression that John Proctor is quite harsh and strict. When the other girls leave Proctor and Abigail start talking, Abigail is flirting with Proctor, she says John- I am waiting for you every night. However he replies with Abby I never give you hope to wait for me This shows that Proctor is the one who is trying to end the affair with Abigail, because he knows he has a family. When the girls are blamed from worshiping the Devil Abigail quickly blames Tituba, the West- Indian slave. Parris, goody Putnam and Hale question and threaten Tituba and she begins to name witches. Abigail and the other girls join in the naming. Tituba confesses because of the threats from Parris. You will confess yourself or I will take you out and whip you to death, Tituba! Tituba feared for her life so felt she had to confess.

Lifestyle in the Suburbs

Lifestyle in the Suburbs Introduction Suburban is an area that lies right away form the city or a town. This idea of suburban living came as a result of the need to change from models with high density housing to low density housing. The new homes that were built were spacious with a lawn or a garden and were adapted by many people who could afford them. The choice of living in the suburbs came with an assortment of reasons ranging from high rates of crime, traffic, noise and busy environment.Advertising We will write a custom essay sample on Lifestyle in the Suburbs specifically for you for only $16.05 $11/page Learn More The environment was also known to be safer for bringing up children. The necessity for quality life, health and well being, safety and better lifestyle called the individuals to work harder so as to triumph over the higher cost that came with it. The preference of living in the suburbs kept one away from environmental pollution such as noise and garbage while givi ng a tranquil place of residence. This essay will discuss lifestyle in the suburbs and the effort that a person must incur to sustain his cost of living. History of Suburban living 18th and early 19th century marked a revolution of many villages and markets as they grew into industrial cities. The growth resulted from industrialization. Initially, there were no building regulations and this made these cities to be dirty without clean sanitary facilities and high populations. In the late 19th Century the government introduced laws in public health which supervised sewage and sanitation. Living in cities was therefore a result of many economic opportunities in the cities compared to the rural areas. Most people in suburban areas were ready to spend more and dig deeper in their pockets, about 47% of their income, to maintain housing and transportation (Kim, 2011, p. 1). Maintenance Cost of Suburban Living It is more expensive to maintain suburban infrastructure development. This is bec ause the cost sharing is between fewer people than in urban areas where higher population shares the cost in paying taxes. Though the cost of buying a house in the suburbs is lower than in the urban, maintenance is expensive. The cost of transport in the suburbs is pricey. Without a car in the suburbs, it is quite troublesome to move about. Personal ownership of a car is therefore compulsory for living in the suburban areas. The cost of moving to and fro is escalated because of driving to work daily. Though the expenses within the house are lower, e.g. the electricity bills and water bills maintenance of the home is highly affected by the use of automobile. A person must travel to work, drive children to school, go for shopping or any other travelling because of unavailability of public means. Safeguarding this car is in addition very expensive. Insurance, maintenance, repairs, gasoline and license fees add more to the cost of this car. This is costly especially for the middle and l ow income. Parking fee for the car is also is another expense that drains ones income.Advertising Looking for essay on social sciences? Let's see if we can help you!

People living in the suburban areas require auto mobiles for their transport. The average is that each family needs a car for convenience. The growth of the suburban domino effect is the demand of oil hence raises the price of the oil. Climate changes as the automobiles emit carbon dioxide which is not absorbed in the air. CO2 leads to rise in temperature (Shaik, 2010, p. 1). Suburban settlement reduces social interactions. Living in the suburbans encouraged privacy and most neighbors became strangers to each other. This caused separation of communities on foundation of their economic status. This was what caused North America to segregate. The effect of se gregation makes the people to be unable to accommodate each other since the society in the suburban rarely share experiences, talents and their way of thinking. This discourages social sustainability (Shaik, 2010, p. 1). Suburban settlement decreases the efficiency of energy use. This is a consequence of using automobiles which increases in number and the distance covered. The people in these areas hardly walk or ride bicycles while traveling, methods which could save a lot of energy (Urbanity, n.d., p. 1). The suburban system brings discrimination to the poor, the elderly and the children. The poor are alienated from the luxurious homes since they cannot afford to purchase their own cars. The elderly people on their second retirement are only allowed to stay in a retirement community and such experience of traveling about is denied to them. Most children of the rich people who live in the suburban areas are able to attend events such as parties and games. So the best social places for children are for those with good economic backgrounds. The high cost is afforded by the children of the rich parents (Urbanity, n.d, 1). Appropriate Technology Appropriate technology is almost compulsory to those living in the suburban areas. There tends to be great dependency on comprehensive technology. The positive side of it is that the suburban people provide meaningful employment to technology companies. High technology applications are often found in the areas of the rich. The cost of living continues to be high in the suburbs. The sustainability cost is higher when there is no sharing of the cost (Wicklein Kachmar, n.d., p. 1). There is more need to have tight security in the suburban. This makes it obligatory to have a security guard as well as technological security systems in the home such as CCTV cameras. Most homes in the suburban have a guide.Advertising We will write a custom essay sample on Lifestyle in the Suburbs specifically for you for only $16.05 $11/page Learn More Benefits of Suburban Living Suburban residents are at a lower risk of health problems than those living in the urban. The congestion in urban areas can encourage a quick spread of diseases. In Most places, the poor live around their work place whereas the rich live outside the cities in places without pollution. The design of houses in cities is mostly to maximize the number of people living in a particular area. Important life commodities such as water and privacy become scarce and this is a cause of many health problems such as tuberculosis at times in the urban depending on the country in question. Recommendations The main aim of these recommendations is to lower the scale of expenses that come as a result of maintenance fee as well as to bridge the social gap that is created by suburban settlement. The suburban developers should create variety of housing and transportation choices. This is by considering different economic classes from high in come earners without discriminating them. The employers should also encourage their employees to telecommute so as to reduce travelling expenses as well as to reduce the traffic (Goodson, 2001, p. 1). Conclusion Suburban living is a choice which is made by people in need of a better environment in terms of pollution, health, security and comfort. This comes with a higher cost of living and mostly segregates the rich from the poor. Maintenance cost of a home in the suburban is quite expensive. Automobiles are the major escalators of the living cost. Security, technology and taxes are also factors that increase the cost of living in the suburban. The suburban lifestyle discourages social interactions and has a high dependence on automobiles which promote inefficient energy use as well as increasing the demand of gasoline which makes it expensive. The developers of these areas should create housing and transport choices so as to incorporate many people by lowering the cost. References Goodson, D. (2009) Suburban housing: a cheaper alternative?

Avoiding Physical Punishment In Child Rearing Essay

, Research Paper Is # 8220 ; saving the rod # 8221 ; botching or salvaging the kid? Is force, bitterness, choler or fright worth the hazard taken when striking him or her. Whether your for or against utilizing physical penalty in kid development, as a parent, you will someday hold to confront this issue. Many parents are taught this method in their childhood, and are non cognizant of any other manner. Often arising from faith, physical or bodily penalty is seen as an of import ingredient in kid raising. This tool is used to carry through entire authorization by the parent and to have entire entry from the kid. Physical penalty may be convenient and achieve impermanent conformity, but produces negative consequences, and should be avoided. HISTORICALLY Punishment day of the months back to early human history. To keep the Torahs that were created for societal life, punishments were developed for the persons who could non stay by them. Authoritarianism changed the grounds behind penalty ; alternatively of protecting society from the felon, it became a manner for the # 8220 ; Chiefs to command the Indians. # 8221 ; It placed the leaders above everyone else, forestalling the people # 8217 ; s sentiments from numbering ; an antidemocratic society. As illustrated by Dreikurs and Grey, # 8220 ; Those in bid were superior and hence right ; those whom they ruled were inferior and hence incorrect if they disagreed with the swayers # 8221 ; ( 66 ) . Physical penalty has been approved in history as # 8220 ; the function of authorization, # 8221 ; as a declaration of power. Penelope Leach provinces, # 8220 ; Physical penalty was one time an recognized portion of any relationship that gave one single legitimate authorization over others # 8211 ; maestro over slave, retainer or married woman ; officer over lower ranks ; jurisprudence hatchet man over jurisprudence ledgeman ; employer over learner # 8211 ; but that is history ; we have cosmopolitan human rights now # 8211 ; cosmopolitan except for kids, that is # 8221 ; ( 126 ) . Teaching entire authorization by the parent, most Conservative Protestants use bodily penalty today as their sires did. In Spare the Child, Philip Greven points out, # 8220 ; Modern signifiers of Christian Fundamentalism portion the same compulsions with obeisance to authorization feature of earlier manners of Evangelical Protestantism, and the same autocratic run evident among 17th # 8211 ; and eig hteenth-century Anglo-American Evangelicals is discernable today, for exactly the same grounds: the coercion of kids through painful penalties in order to learn obeisance to divine and parental authorization # 8221 ; ( 198 ) . The thought many old ages ago is obvious, society felt that physical penalty was necessary for obeisance. With survey and research over clip, successful kid raising has changed to bring forth better consequences. Dr. Benjamin Spock adds, # 8220 ; In the olden yearss, most kids were spanked, on the premise that this was necessary to do them act. In the 20th century, as parents and professionals have studied kids here and in other states, they have come to recognize that kids can be well behaved, concerted, and polite without of all time holding been punished physically # 8221 ; ( 437 ) . Recognizing the impact this antique method can hold on a kid, society is altering their positions on how we should train. We are traveling off from bullying and hurting tactics to more effectual, positive methods. EFFECTS / RESULTS To be more effectual in child raising we must foremost recognize the unsought consequences that can come from utilizing physical penalty. When a parent strikes a kid, they are learning that kid to cover with jobs in a violent mode. As an opposition to bodily penalty, Murray Straus writes, # 8220 ; I am non stating the grounds is unequivocal. I believe future research will corroborate the decisions that the force we so abhor and fright has portion of its beginnings in the actions of loving parents who, by paddling kids, accidentally learn force? We should move now because bodily penalty is force. Therefore, irrespective of whether it reduces what most people think of as the existent force, a society that stops hitting kids is a less violent and more humanist society # 8221 ; ( qtd. in Ellison paragraph 22 ) . Negative influence is another disadvantage of physical penalty. An grownup influences a kid utilizing physical penalty, exposing a deficiency of self-denial by the parent. Physical penalty besides implants bitterness, choler and fright of the parent. Causing bitterness, choler or fright in a kid can ensue in # 8220 ; blowback # 8221 ; of the penalty. Hiting a kid displays a deficiency of regard for them and engender rebellion. For illustration, metres are placed to necessitate payment for impermanent parking. Exceeding the clip bound or declining to pay can ensue, if your caught, in a all right. Just being cognizant of the effects of misdemeanor can assist to implement this regulation. However, many people will park without paying if they feel they can acquire off without a punishment. Similarly, a kid having a spanking will reiterate the act if he or she realizes he or she can avoid acquiring caught. It has been argued by professionals that the usage of physical penalty has been a factor in forestalling self-esteem, assurance, creativeness and rational independency ; doing delinquency, depression and disaffection. Used excessively frequently, physical penalty can lose its steam, and lead to child maltreatment. Option There are successful, alternate methods in training for physical penalty. Keeping consistence, being sort yet house is a critical portion of utilizing these alternate methods. Understanding it is the importance that we place in an issue, and non the step of penalty given, that makes the difference. Penelope Leach writes, # 8220 ; Many kids have so learned to postpone bedtime about indefinitely, but merely because parents are excessively tired to follow through. If those same kids need medicine for a chronic unwellness such as asthma, they take it without a murmor because parents are convinced that it truly affairs and are hence clear, confident and consistent in their insisting # 8221 ; ( 125 ) . Of the many alternate methods for subject, a few to discourse are the # 8220 ; Law of Reinforcement, # 8221 ; # 8220 ; Time-out, # 8221 ; # 8220 ; Immobilization # 8221 ; and # 8220 ; Logical or Natural Consequences. # 8221 ; The # 8220 ; Law of Reinforcement # 8221 ; was devised by the first educational psychologist, E.L. Thorndike. It was latter revised and polished by B.F. Skinner. This method is simple, a kid will reiterate an act or behaviour if the consequences are delighting to him or her. As noted by Dr. James Dobson, # 8220 ; Behavior which achieves desirable effects will repeat # 8221 ; ( 64 ) . Something to see with this method is the wagess promised as a consequence of good behaviour must follow instantly. They can non be long-run wagess, such as a friend remaining nightlong subsequently in the hebdomad, or a holiday subsequently in the twelvemonth. Exploitation wagess at the incorrect clip, such as assuring them to a kid that is in rebelliousness, can besides be a error. Furthermore, the wagess need non be material, forestalling them from going graft. Therefore, utilizing verbal support ( personal regards ) can be much more effectual. Another method in subject is # 8220 ; time-out # 8221 ; . This removes the kid from a state of affairs until he or she changes the improper behaviour and regains his or her calm. This method should non be used excessively often, and should ever follow with an account of why the behaviour is non acceptable. Harmonizing to Larry Reibstein, # 8220 ; The Newsweek canvass showed that 71 per centum of parents frequently or sometimes used timeouts # 8221 ; ( 64 ) . Immobilization is a technique used less frequently for kids runing from 7 to 14 months that can non command their behaviour of, for illustration, hitting another kid or an grownup. After a warning has been given, the kid should be placed on your lap or a chair and held down until the kid is unagitated and you can explicate to him or her the ground this is unacceptable. This technique is limited in many ways and should be used carefully, and at a lower limit. Covering with a kid with Logical or Natural Consequences can be an effectual option. Teaching the kid the effects that result from a specific action can either be logical or natural. Logical significance if a kid does something incorrect, the effects can be bad, typically brought approximately by the parent. Natural significance if a kid does something incorrect, the effects can be bad, typically brought about by some kind of physical world. Dr. Loren Grey acknowledges the logical method, # 8220 ; Even though the consequence is arranged by the parent, the kid sees it as his ain action and normally a repeat of the consequence is non needed to act upon alteration # 8221 ; ( 47 ) . Refering natural effects, Dr. Grey writes, # 8220 ; If a little kid runs his caput into a tabular array and hurts it, no warnings or repeated illustrations are necessary to convert him to avoid that in the hereafter # 8221 ; ( 46 ) . Contained in this paper are a few of the many options to physical penalty. There are many more ways to convey about alteration in a kid # 8217 ; s behaviour. Striking a kid is a certain manner to learn force as a solution to jobs, produce bitterness towards the parent and transfuse choler or fright in the kid. Becoming more educated with the options, parents can play an of import function in supplying a less violent society. Along with these options, parents should be sort yet steadfast and should ever keep consistence. Dobson, James. Dare to Discipline. Wheaton, Ill: Tyndale House Publishers, 1970.

Relationship between mothers age , birth weight and gestation Essay

Relationship between mothers age , birth weight and gestation - Essay Example post natal weight loss.The mothers socio-economic status has been listed as a major factor underlying low birth weights though other factors have been documented. While there is a strong correlation between birth weight and gestation period, the birth weight and age correlation seem to be an interesting as we would like to know at which age are mothers more healthy at giving birth. Age and parity affects the weight of the fetus though there is low correlation between the mother’s age and weight of fetus (Jen, 1969 p.187). It has also been shown that the birth weight average for first born babies in very young couples is low (Mary and Perose n.d. p.150). It is known that the age of the mother will affect the conditions necessary for good fetal birth weights. Hypothesis; mothers age greater than 35 give low birth weight 50 sets of data containing age of mothers and the birth weight of their corresponding babies were systematically sampled from a sample of 1148 entries at the oxford street hospital. Samples were picked at intervals of 23 to constitute a representative sample. The samples were analyzed using Microsoft excel software. Table 1 is a representative sample of the data collected for the analysis. From figure 1 and figure 2 it can be observed that the sample is normal distribution and therefore statistical methods of analyzing the data can be applied. From the stem and leaf diagram we can tell that most mothers were in their 20’s whereas only two mothers were below 20years of age. From table 1 we can estimade that the mean, mode and median will likely fall within the 20’s age group. The mean birth weight was 3.46 Kg whereas the mean age for the mothers was 29.16 years. The median for the birth weights of the population was 3.42 Kg and the median age was 28 years. The most common birth weight was 3.32Kg and the common mother’s age 23 years. 25% of the birth weights were below 3.19, whereas half of the birth weights were below3.42 and 75% of the
