Statistics for Management Essay Example for Free

Statistics for Management Essay Q1. Define â€Å"Statistics†. What are the functions of Statistics? Distinguish between Primary data and Secondary data. Answer: Statistics: Statistics as a discipline is considered indispensable in almost all spheres of human knowledge. There is hardly any branch of study which does not use statistics. Scientific, social and economic studies use statistics in one form or another. These disciplines make-use of observations, facts and figures, enquiries and experiments etc. using statistics and statistical methods. Statistics studies almost all aspects in an enquiry. It mainly aims at simplifying the complexity of information collected in an enquiry. It presents data in asimplified form as to make them intelligible. It analyses data and facilitates drawal of conclusions. Important functions of statistics: Presents facts in simple form: Statistics presents facts and figures in a definite form. That makes the statement logical andconvincing than mere description. It condenses the whole mass of figures into a singlefigure. This makes the problem intelligible. Reduces the Complexity of data: Statistics simplifies the complexity of data. The raw data are unintelligible. We make themsimple and intelligible by using different statistical measures. Some such commonly usedmeasures are graphs, averages, dispersions, skewness, kurtosis, correlation and regressionetc. These measures help in interpretation and drawing inferences. Therefore, statisticsenables to enlarge the horizon of ones knowledge. Facilitates comparison: Comparison between different sets of observation is an important function of statistics. Comparison is necessary to draw conclusions as Professor Boddington rightly points out.† the object of statistics is to enable comparison between past and present results to ascertaint he reasons for changes, which have taken place and the effect of such changes in future. Soto determine the efficiency of any measure comparison is necessary. Statistical devices likeaverages, ratios, coefficients etc. are used for the purpose of comparison. Testing hypothesis: Formulating and testing of hypothesis is an important function of statistics. This helps indeveloping new theories. So statistics examines the truth and helps in innovating new ideas. Formulation of Policies: Statistics helps in formulating plans and policies in different fields. Statistical analysis of data forms the beginning of policy formulations. Hence, statistics is essential for planners,economists, scientists and administrators to prepare different plans and programmes. Forecasting: The future is uncertain. Statistics helps in forecasting the trend and tendencies. Statisticaltechniques are used for predicting the future values of a variable. For example a producerforecasts his future production on the basis of the present demand conditions and his pastexperiences. Similarly, the planners can forecast the future population etc. considering thepresent population trends. Derives valid inferences: Statistical methods mainly aim at deriving inferences from an e nquiry. Statistical techniques are often used by scholars’ planners and scientists to evaluate different projects. These techniques are also used to draw inferences regarding population parameters on the basis of sample information. Statistics is very helpful in the field of business, research, Education etc., some of the uses of Statistics are: Statistics helps in providing a better understanding and exact description of aphenomenon of nature. Statistics helps in proper and efficient planning of a statistical inquiry in any field of study. Statistical helps in collecting an appropriate quantitative data. Statistics helps in presenting complex data in a suitable tabular, diagrammatic andgraphic form for any easy and comprehension of the data. Statistics helps in understanding the nature and pattern of variability of aphenomenon through quantitative observations. Statistics helps in drawing valid inference, along with a measure of their reliability about the population parameters from the sample data. Any statistical data can be classified under two categories depending upon the sources utilized. These categories are, 1. Primary data 2. Secondary data Primary Data: Primary data is the one, which is collected by the investigator himself for the purpose of aspecific inquiry or study. Such data is original in character and is generated by surveyconducted by individuals or research institution or any organisation. 1.The collection of data by the method of personal survey is possible only if thearea covered by the investigator is small. Collection of data by sending theenumerator is bound to be expensive. Care should be taken twice that theenumerator record correct information provided by the informants. 2.Collection of primary data by framing a schedules or distributing and collecting questionnaires by post is less expensive and can be completed in shorter time. 3.Suppose the questions are embarrassing or of complicated nature or the questionsprobe into personnel affairs of individuals, then the schedules may not be filledwith accurate and correct information and hence this method is unsuitable 4.The information collected for primary data is mere reliable than those collectedfrom the secondary data.Importance of Primary data cannot be neglected. A research can be conducted withoutsecondary data but a research based on only secondary data is least reliable and may have biasesbecause secondary data has already been manipulated by human beings. In statistical surveys it isnecessary to get information from primary sources and work on primary data: for example, thestatistical records of female population in a country cannot be based on newspaper, magazine and other printed sources. One such sources are old and secondly they contain limitedinformation as well as they can be misleading and biased. Secondary Data: Secondary data are those data which have been already collected and analysed bysome earlier agency for its own use; and later the same data are used by a different agency. According to W.A.Neiswanger, ‘ A primary source is a publication in which the data are published by the same authority which gathered and analysed them. A secondary source is apublication, reporting the data which have been gathered by other authorities and for which others are responsible’. 1.Secondary data is cheap to obtain. Many government publications are relatively cheapand libraries stock quantities of secondary data produced by the government, bycompanies and other organizations. 2.Large quantities of secondary data can be got through internet. 3.Much of the secondary data available has been collected for many years and therefore itcan be used to plot trends. 4.Secondary data is of value to: The government help in making decisions and planning future policy. Business and industry in areas such as marketing, and sales in order to appreciate the general economic and social conditions and to provide information on competitors. Research organizations by providing social, economical and industrial information. Secondary data can be less valid but its importance is still there. Sometimes it is difficult toobtain primary data; in these cases getting information from secondary sources is easier andpossible. Sometimes primary data does not exist in such situation one has to confine the researchon secondary data. Sometimes primary data is present but the respondents are not willing toreveal it in such case too secondary data can suffice: for example, if the research is on thepsychology of transsexuals first it is difficult to find out transsexuals and second they may not bewilling to give information you want for your research, so you can collect data from books orother published sources.

Noahs Ark vs. Jurassic Park :: Biology Essays Research Papers

Noah's Ark vs. Jurassic Park As the human population of the world continues to increase the flora and fauna of the planet are becoming an increasingly smaller part of the picture. Environmentalist and conservationists all over the globe are working hard to find strategies and methods for the preservation of disappearing creatures and species. An increasingly popular idea that would allow for great benefits in the field of conservation became apparent in 1996 with the cloning of sheep by the name of Dolly. Since then the scientific debate on the relationship between cloning and conservation has ensued. Although the answer to that question remains on the horizon, cloning for helping endangered species is a process that may become a frequent procedure in the future. When one thinks of cloning generally the first idea that pops into your mind is a large tube filled with some creature attached to a lot of tubes. Cloning actually, is a much more complicated and difficult process. Cloning, scientifically defined is, "asexual reproduction or as the creation of genetically identical individuals" (1). In the cloning process the DNA of one individual creature is "copied" into the cell, or embryo, of another and then that embryo develops into a baby and proceeds down the process of birth and embryological development. Currently, many scientists believe that if the DNA of endangered species is rescued and preserved that the DNA of that species could undergo the cloning process and thus produce a clone of that species. The results of this cloning process would be enormous or it "will open a new front in the battle to preserve the Earth's biodiversity by cloning endangered gorillas, tigers and other rare species" (2). Cloning of endangered species would be a monumental achievement for the scientific community. Many people when they think of cloning picture sometime weird science fiction creature in a test but in real life the idea of cloning could be a valuable tool for the environmental community and it would be a process could vastly improve the current situation of endangered species. Part of the reason why the cloning process is so highly revered is because of the level of complexity and the multiple details that must develop accordingly for the process to work. Robert P. Lanza says, "It is a deceptively simple-looking process. A needle jabs through the protective layer surrounding an egg. A research assistant sucks out the egg's nucleus, which contains the majority of a cell's genetic material, leaving behind only a sac of gel called cytoplasm.

Muslim Stereotypes in the Media Essay

The media over exaggerates their representation of the Muslim population portraying them as violent terrorists and a threat to most nations/countries. Stereotypes abound in any and every form of media we can listen to, read, or watch today. Stereotypes create recognition in people and stir emotions – from anger to fear, or even empathy. News reports on religion generally use outrageous stereotypes of the population of the particular religion. This is evident in the representation of Muslims whenever they pop-up in news stories. Our views and opinions are often shaped by the media – the news, TV shows, movies, magazines and newspapers. Many people take the views depicted in these and claim them as their own without thinking or researching it more. Cultural Theorist Stuart Hall states that the messages in media, â€Å"intersect with the deep semantic codes of a culture and take on additional, more active ideological dimensions.† This means that they build on the cultural and social anxieties of a given time and also reflect then back into the culture, therefore reinforcing them and adding to them. The problem with this is that the media almost always leaves bits and pieces out and portray only the parts they think we want to see to meet our expectations. The kids movie, â€Å"Aladdin† is one which given a skewed view of Muslim people. In the opening scenes of the theatrical release, the theme song states that Aladdin hails â€Å"from a faraway place, where the caravan camels roam, where they cut off your ear if they don’t like your face. It’s barbaric, but hey, it’s home.† Throughout the movie Muslims are repeatedly depicted as scheming, mystical, violent, stupid or greedy Arabs. Everything from costuming to voice tones, facial features and references to Allah build a very stereotypical and false image of Muslims. One of the reasons why this is an incorrect stereotype is that most Muslims are not even Arabic with only about 18% of the 1.6 billion Muslims being Arabic. So why do we as westerners make this assumption that all Muslims are Arabic? I think this is because we don’t look into the figures and information for ourselves we just assume that these negative stereotypes are the truth and by doing this it has become our reality. In the case of Aladdin, this fairytale is viewed by children from such a young age that it becomes a part of their subconscious without them even realizing they have been fed a stereotype. More modern TV shows such as â€Å"Homeland† represent Muslims as fanatic Arab terrorists posing a threat to countries and nations around the world. This is mainly a western representation and is a typical negative stereotype of Muslims that most people believe and accept as the truth. Although this may be an accurate representation of a small minority of the Muslim population, in my opinion this is a false stereotype of the majority of the population. The media has generalised their opinion based on a small minority to all of the Muslim population and sensationalized it to heighten cultural anxieties. This opinion and stereotype has caused much tension between westerners and the general Muslim population in the past and the present. The media reports involving Muslims and Islam in general have become more frequent, with the racist, stereotype images and remarks becoming more and more accepted as normal, especially in the news, entertainment and social media. The media has been targeting religion and more specifically Islam since the events of the 9/11 planted a seed of fear for terrorists and religion in general. Media including Hollywood and the filmmakers have become worse in their racist opinions of Muslims portraying them more and more as brutal, heartless, uncivilised religious fanatics and money-mad cultural â€Å"others† bent on terrorising civilised Westerners. Perhaps it is time that the media realizes that instead of investing in negative stereotypes, there is a positive impact which can be obtained by using counter-stereotypical fictional depictions to turn the tide on societies prejudicial attitudes. religionandmediacourse.blogspot.com.au/2010/11/representations-of-islam-in-media.htm maddysreligionandspirituality.blogspot.com.au/2013/05/week-9-10-religious-racism-and-media.html asiainstitute.unimelb.edu.au/__data/assets/pdf_file/0008/571625/akbarzadeh-islam-media.pdf mediasmarts.ca/diversity-media/religion/media-portrayals-religion-islam teachmideast.org/essays/26-stereotypes/38-stereotypes-of-arabs-middle-easterners-and-muslims http://www.theguardian.com/tv-and-radio/2012/oct/13/homeland-drama-offensive-portrayal-islam-arabs http://racerelations.about.com/od/hollywood/a/5-Common-Arab-Stereotypes-In-Television-And-Film.htm http://srambeau.wordpress.com/2010/10/15/representations-of-arabs-in-disneys-aladdin/ http://www.theguardian.com/media/2007/jan/25/broadcasting.race

Ethical and Legal Dilemmas of Surrogacy Essay - 2979 Words

Ethical and Legal Dilemmas of Surrogacy Christie Blackwell HCA 322 Dr. Nine Bell June 17, 2013 Ethical and Legal Dilemmas of Surrogacy Many individuals have a life plan consisting of college, marriage, and then children. After numerous methods of conception, many couples are still unable to conceive a child. A woman who enters into a contract with a couple, agreeing to carry and birth a child, then hand that child over to the contracted couple, who is often unable to conceive own their own naturally is considered surrogacy (Pozgar, 2012). Surrogacy raises many ethical and legal issues for all parties involved. Is it moral or immoral to enter into an agreement with a woman to birth a child for money? What are the†¦show more content†¦On the flipside on the issue, can it not also be viewed that allowing these women to do as they see fit with their bodies as economic empowerment? The money provided to these women can used for various financial means outside of taking care of medical heath care for themselves and the child. The amount provided to each female varies depend ing on what she and the couple feel is sufficient, therefore any extra monetary compensation can used to help the women relieve themselves from other debts. Autonomy does provide the right that women get to choose their reproductive rights and that includes bearing children for those who cannot do so or for monetary stability. Suggesting that surrogacy dehumanizes her is another form of paternalism. Paternalism limits one’s autonomy for their own good (Pozgar, 2012). Some view altruistic surrogacy as a form of exploiting the surrogate. There is no monetary compensation to woman placing her health and well-being on the line for another’s benefit. However, it can also be held that the woman knowingly entered into the agreement with full disclosure of the risks and benefits to her health and body. Again, autonomy and justice are extremely prevalent ethical principles to explore when discussing the topic of surrogacy.
