## CHECK THESE SAMPLES OF Regression/ANOVA (probability and statistics)

...The **ANOVA** or one-way analysis of variance is used in research and empirical studies to compare certain variables or results. Basically, it is used todetermine whether two values are **statistically** significantly different. This is most often utilized when a research aims to compare groups of people or subjects based on certain elements.

So, with α = 0.05, the critical value of F in this analysis of variance test was F0.05 (1, 4) = 230. Since computed F (FC) is less than Tabulated F (FT), Ho is accepted. This is because the result of the “Analysis of Variance” (ANOVA) shows that the computed F (12.43) is less than the tabular values of F-statistics (230) at 0.05 degree of freedom (1, 4). This means that there is no significant difference between the variables of amounts claimed and amounts reimbursed in relation to “legitimate” expense claims.

The resultant R Square 0.7565 is very close to 1 and it is above 0.75 which means that the correlation is near normal curve distribution, so, it is interpreted as a very high positive corr...

... output means it is less than 0.001 (or 0.05).
**ANOVA** uses F distribution (F test **statistic**). p-value is referred to as observed significance level (α), which is the **probability** of making a Type I error that is rejecting the null hypothesis when it is in fact true. P-value is based on the test **statistic** F, and between and within degrees of freedoms. Minitab output provides p-value (P), thus, we do not need to calculate it.
The results of the test were **statistically** significant, F(3, 14) = 23.39, p < .001. Thus, the null hypothesis is rejected; there are differences in the % water content between the group of kidneys exposed to varying times of ischemia. The % water content in control group (X ± SEM: 79.09 ± 0.18%) is less compared to 30 min...

...**ANOVA** Question: Ive done a one-way **ANOVA** with 4 groups and obtained a **statistically** significant F value. Now I want to see if any of the groups are different from each other, so I need some way to compare them--ie., A vs. B, A vs.C, A vs.D, B vs C, B vs D and C vs. D. I have a nice chance here to use my t test skills and do these 6 t-tests. Why might I not want to do that? What can you suggest instead?
Answer: **ANOVA** is used to determine whether there are differences among the means of two or more populations. As stated in the question the one-way **ANOVA** with 4 groups is **statistically** significant. This suggests that the means are all not equal and at least one group is different from another. However, **ANOVA** test does not say anything about...

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...

Abstract
In this work, the author explored the role of **probability** in inferential **statistics**. Man has discovered several **probability** distributions. Some of these **probability** distributions include the binomial, hypergeometric, normal, chi-square, and several other **probability** distributions. Populations or **statistics** are assumed to follow one of these several **probability** distributions and these are used to estimate population parameters as well as test hypotheses on the population. The standard normal distribution, for example, is used to draw inferences on population parameters such as the population mean. The t-**statistics** is used for inferential purposes involving small samples or where the population variance is unknown. Finally...

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...

... Abortion Introduction Abortion is defined as the termination of pregnancy before the child is born or before the child canbe in a position to live independently outside the mother’s womb (Lanier 14). An abortion that occurs naturally before a pregnancy reaches 24 weeks is referred to as a miscarriage. However, abortion can also be induced. Induced abortion can be prescribed by the doctor in case there is a medical risk to the mother, or it can be a decision by the mother due to their own reasons (Lanier 17). There are different laws of abortion depending on the country or state that one lives in. This paper will focus on abortion in California.
