## Extract of sample "ANOVA"

Assignment 3 (Part 3) – Statistical Analysis of Data – ANOVA (One Way Analysis of Variance) A. Research Question: Is there a difference in the % water content between the groups of kidney exposed to varying times of ischemia?
B. Null Hypothesis:
There is no difference in the % water content between the group of kidneys exposed to varying times of ischemia. In other words, there is no effect of varying times of ischemia on % content of water in the group of kidneys. In symbolic form,
H0: µ1 = µ2 = µ3 = µ4 (all the means are equal)
(1-Control, 2-30 min ischemia, 3-60-min ischemia, 4-120 min ischemia)
The alternate hypothesis will be
H1: Not all the means are equal (at least one mean is different)

## CHECK THESE SAMPLES OF ANOVA

### ANOVA

...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. The research conducted by Herrera and Lim (2003) aimed to analyze the job satisfaction of certified athletic trainers specifically those who are employed by selected NCAA Division IAA institutions with football programs. The study involved a sample of 138 certified athletic trainers. The trainers held various positions in the program and had varying levels of education and job experience...

### Applying ANOVA and Nonparametric Tests

...ANOVA which means Analysis of Variance is a statistical tools used for analyzing the level of variations between two population groups. It is used totest hypotheses concerning means when we have several populations. It is used to test the hypothesis that the means of two or more groups are equal with the assumption that, the sampled populations are normally distributed. Other wise, it can be referred to as distribution based test (Doane, D & Seward, L 2007) Non-parametric test on the other hand is the opposite of parametric test. Parametric test operate under the assumption that, the sample is normally distributed and it is used to analyze non-quantitative data; it deal with qualitative data. For non-parametric tests,...

### Describe how you understand ANOVA

...Understanding the ANOVA When attempting to examine the potential differences between three or more groups of scores; it is necessary to examine thesegroups simultaneously. Pair wise comparisons are not only tedious and time consuming; but also prone to error. Since we have to accept a minimum possibility of error for each comparison made; the chances for type I error to occur across a large number of comparisons keeps increasing exponentially with the number of comparisons (Guilford, & Fruchter, 1973). For three groups, there will be 3 comparisons; for four groups there will be six comparisons and so on. In order to contain the error and compare all groups simultaneously, the Analysis of Variance or ANOVA may be used. The ANOVA... is a...

### Regression/ANOVA (probability and statistics)

...Statistics Report The aim of this paper is to present a report on the comparison of home and away scores of each country using regression/ANOVA. The report will also include tests that were carried out to test if the scores of different countries exhibit any form of correlation. Correlation between the score of the countries when playing home and away and the interaction between the sum of score of different countries will also be reported on. The eight countries that were included in this survey are Australia, New Zealand, Pakistan, Pakistan, India, South Africa, England, Sri Lanka, and West Indies. Six pairs of scores (home and away) were recorded for each country The overall average score for both home and away...

### ANOVA

...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...

### Anova

...ANOVA ANOVA One field that has been applied in a variety of s is statistics. Both scientist and no scientists interact with numbers almost every day of their lives. Statistics plays a big role in informing the audience, changing their opinions as well as well as creating curiosity. This paper will look how analysis of variance can be used in enhancing understanding of a given issue. Ideally, ANOVA is best suited when an analysts wish to compare the means of at least two groups or level of independent variables (Steinberg, 2010). One issue I would like to explore is with regards to individuals eating fast foods based on their age. It has been alleged that younger members of the society, especially from both developed and developing...

### ANOVA discussion

...Analysis of Variance of One-way ANOVA and two-way ANOVA One-way anova and two-way anova will be looked at through the study of ways in which fertilizers contribute to the yield of maize. When fertilizer is applies, each having different quality, on different plots of land and each having maize seedlings. The yield from every plot is analyzed and recorded then the differences in the yields obtained from every plot analyzed. In this study, the different quantities obtained from every plot are called levels while the fertilizer is called a factor. This type of analysis describes one way and two-way anova since it is based on one factor, fertilizer. The study...
