Now a day’s ANOVA is also more commonly used in the field of Agriculture. Another main advantage of using ANOVA is that it can be used even if the number of observations in each group vary. In particular, ANOVA helps to identify how a particular treatment works and how long it lasts. ANOVA is the most preferred model in the field of pharmaceuticals and medical research because it helps to find out how effective are the two different types of treatment and how durable they are. In such cases, ANOVA becomes more reliable and effective. It is not reliable when there are more than two samples to be compared. The t-test compares the means between two samples and is also easy to conduct. There are only two tests which can yield the same results – t-test and ANOVA. This is because it is easy to compute manually using simple algebra rather than complex calculations. Though there are different methods like hypothesis testing, partitioning of a sum of squares and others ANOVA is given the first preference these days. The null hypothesis of ANOVA states that all means are equal and the alternative hypothesis states that at least one is different. ANOVA assesses the importance of one or more factors by comparing the variable means at different factor levels. It is used to test the specific differences between the means. It is a statistical method which is used to test the difference between two or more means.

A sociologist is interested in knowing if the amount of income a person earns varies according to his or her upbringing. For example, an environmentalist is interested in knowing if the average amount of pollution varies in several bodies of water. 11.3: Prelude to F Distribution and One-Way ANOVA Many statistical applications in psychology, social science, business administration, and the natural sciences involve several groups.11.2.3: Comparison of the Chi-Square Tests.The null and the alternative hypotheses for this test may be written in sentences or may be stated as equations or inequalities. You use a chi-square test (meaning the distribution for the hypothesis test is chi-square) to determine if there is a fit or not. ![]() For example, you may suspect your unknown data fit a binomial distribution. 11.1: Goodness-of-Fit Test In this type of hypothesis test, you determine whether the data "fit" a particular distribution or not.11.0.1: Facts About the Chi-Square Distribution.This distribution is called the chi-square distribution. ![]()
