Detailed explanation-1: -A t-test is an inferential statistic used to determine if there is a statistically significant difference between the means of two variables. Analysis of variances (ANOVA) is a statistical examination of the differences between all of the variables used in an experiment.
Detailed explanation-2: -The groups can be compared with a simple chi-squared (or Fisher’s exact) test. For normally distributed data we can use ANOVA to compare the means of the groups.
Detailed explanation-3: -Analysis of variance (ANOVA) is used to test for differences among three or more population means. It allows for multiple comparisons while holding the probability of a type I error (rejection of a true null hypothesis) at a preselected level.
