...?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 ...

The link between GDP and the change in the sales of the housing and real estate units is evidenced by the data on the performance if these two variable over time. The data from the department of labor and economics show that these two variables have a strong positive relationship. This is evidenced by the great global economic and financial crisis of 2009 that negatively affected the housing and real estate sector through the housing bubbles. These changes in the GDP...

...**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...

Once the decision is made that the best way to answer the research problem is by means of quantitative research, there are a number of important aspects, specific to quantitative research, that need to be considered. These aspects include some basic terms, method of data collection, data capturing and editing, **statistical** analysis, interpretation and report writing. These aspects will now be discussed.

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...

...; 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...

..., 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...

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...

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...

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...

...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...

...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.
