The findings of the statistical analysis is presented and discussed in this paper.
Data on Well Being Index and Quality of Work and Life for 50 states and / or congressional district was collected and recorded in MS Office Excel spreadsheet. Descriptive Statistics for well being index and work and life quality was then obtained using MS Office Excel Data Analysis Tool. This was done to get a feel of these indexes i.e. well being index and work and life quality across all the 50 states / congressional districts of USA. The findings of this analysis are presented in Table 1, in the Appendix. It is better to examine and discuss the important statistics obtained from this analysis for each of these indexes – well being index and work and life quality.
Summary statistics of well being index for all the 50 states / congressional districts is presented in Table, in the Appendix. The values for mean, median and mode are 65.47, 65.75 and 66.3 respectively. These parameters are measures of central tendency i.e. the central value around which actual well being index of different states lies. Another important statistics of well being index is standard deviation. Its value is 1.69. This is a measure of dispersion of the actual values around the mean value.
Now let us examine, whether Maryland lies among all the 50 regions with respect to well being index. Well being index for Maryland is 67.1% (Table 2, in the Appendix). This means Maryland has above average well being index among all the 50 regions under consideration. It is important to examine whether the difference from the mean is significant. To do so 95% confidence interval for mean well being index was determined. This confidence interval is

...?Because there are 50 numbers, we can divide these numbers into groups of 10 (5 groups). Next we subtract the lowest number from the highest number (76 — 16 = 60). After this, we will divide the difference by the number of groups that we came up with (60 / 5 = 12). Once we get the class width (12), we add it to the lowest number in order to get the lowest class limit (16 + 12 = 28). If we keep on repeating this step, we can determine all the appropriate class limits (28 + 12 = 40, 40 + 12 = 52, 52 + 12 = 64, and 64 + 12 = 76). Because these are the maximum limits, we have to subtract 1 from each class limit (16 + 12 — 1 = 27, 28 + 12 — 1 = 39, 40 + 12 — 1 = 51, 52 + 12 — 1 = 63). Now that we have worked this out, we can create... there are 50 ...

...Statistics Introduction Carbon dioxide’s concentration in the atmosphere is changing from time to time across the years. There are a number of evidences which show that the concentration of atmospheric carbon dioxide has been steady increasing globally. This rise is attributed to increasing human and industrial activities across the globe. Unlike moisture in the atmosphere, carbon dioxide is mixed well in the atmosphere thus its circle can go unnoticed due to relatively slow changes. The level or rather the amount of carbon dioxide in the atmosphere is measured easily because it is a greenhouse gas; causing surface warming. Therefore, this paper presents carbon dioxide data and a presentation of its trend over the years. In addition...

Abortion Facts and Statistics

Whether legal or not, every year millions of individual women around the world— of all cultural, religious, and economic backgrounds— seek out abortion when they cannot carry a pregnancy to term.

At present almost two-thirds of the world’s women live in countries where abortion may be legally obtained for a broad range of social, economic or personal reasons. When abortion is made legal, available and safe, women’s reproductive health improves. When women can avoid births that are unwanted, mistimed, or too numerous, their children are more likely to survive and be healthy.
 
It has long been recognized that the number of abortions can be effectively reduced by educating people on...

How Does Statistics Help Create Medicines

...; Esser, 2001). Randomization is necessary to generate comparable groups of patients from a population. The new drug must establish a difference in efficacy from a control (or placebo) with statistical assurance. The parallel or Latin square designs are used for randomization in traditional statistics. A blinding is also the part of design where the patient and investigator both remain unaware of the treatment. Blinding prevent biases in data collection and analysis (Chow & Shao, 2002). They further suggest that the statistician should determine a sample size in consultation with the physician. An appropriate test and significance level is selected with a null and an alternative hypothesis. A large sample size is preferred particularly...

Probability and Inferences in Statistics

..., the chi-square statistics are used for inferential statistics related to correlations and associations. These are only some of the distributions but they indicate nevertheless the value of probability distribution for inferences in statistics. I. Introduction In making inferences on the population based on sample characteristics, man used probability distribution or probability density functions (McClave et al. 172-173; Schaum 55). Probability distributions or density functions associates a numeral to a probability value. Probability density functions are curves represented by mathematical equations that best capture the characteristics of the curve. In turn, the curves or the areas under the curve are associated with probability level...

Statistics and Quantitative Methods

The method is also not sensitive to variation in the value of money over time. However, it is easy to use and can be used to make a quick assessment of investment viability using existing data (Groppelli & Nikbakht, 2006: pp. 157-158).

Net present value (NPV) takes into account the value of money over time and uses the present value of future cash flows (Lasher, 2008: p. 426). This present value is compared with the initial investment and decision taken on whether the investment is viable over the long term or not. NPV is, therefore, a difference between the present value and the initial investment. If NPV is positive, the project is viable, and if it is negative, the project may be rejected. NPV uses the discount r...

Statistics of Offenders to Commit Suicide

A more serious suicide problem in correctional facilities, which has come to the fore in recent times, is the gender disparity in the cases of prisoner self-harm and attempted suicide. It is rather intriguing that while they comprise only about 5% of the prison population, female prisoners are observed to attempt more self-harm and attempt suicide compared to males. Notably, between 20% and 24% of female prisoners self-harm while between 5% and 6% of male inmates self-harm every year. The study also found out that cases of self-harm were 30 times higher in female prisoners compared with the general UK population rates, which were reported to be at 0.6%. Hence, this study seeks to establish whether or not, female prisoners attempt...

The Statistics of Abortion in the USA

Despite the emphasis placed on the ethical status of abortion in the United States only surged in the 20th century, the truth is that abortion has existed for a long time in human history. In earlier centuries, women used different techniques to terminate pregnancies if they were categorized as unwanted or risky for the mother. This was the case in many continents a fact that saw abortion a common option in Europe in the 18th century. However, the 19th century brought about a change in the perception of abortion. Laws banning abortion were formulated and reinforced in different regions (Bartkowski et al, 2012). In the United States, the 20th century, was a defining period in the debate surrounding abortion. Prior to 1973, abortion...

The Role of Statistics in Decisionmaking

...sample), carefully selected to represent the all population. Analyzing such a small data is easier and cheap as compared to analyzing the whole population. It is worth noting that population is either infinite or finite and sometimes, in the process of analyzing, sample may be destroyed e.g. testing compression strength in concrete bricks. Therefore, it is advisable that the sample must be representative of the population so that whatever conclusion made based on the sample infer also to the population. This is never absolutely certain hence inductive or statistical inference. The phase of statistics that only describe and analyze a given data without drawing conclusions or inferences about a population is descriptive or deductive...

The Statistics on Abortion in California

...m http://www.californiansforlife.org/education/abortion-facts-for-california/). The penalty is little and affordable to most Americans. Therefore, the law is not strict enough to prevent people from performing unlawful abortions. The fines are not hefty and hence do not help in preventing people from performing abortions. The law in California permits abortion during the early stages of the pregnancy and restricts it during the later stages of pregnancy. However, it is clear that the law contributes to increased abortion cases since it is not strict. The law on abortion should contain certain clauses that mind the health of the patient regardless the stage of the pregnancy. Statistics of abortion in California In the year 2008, the...
