When testing for significance of variables’ mean there are two techniques used depending on the number of variables in question. When the variables are more than 2 we use analysis of variance (ANOVA) but when they are less than two we use t-test. Therefore, ANOVA is basically analysis tool used in statistics that splits data into symmetric and random factors. For us to use ANOVA the variables should be identically and independently distributed. It mainly looks at the tests within the group of data and within groups.
