Analysis of variance (ANOVA) is comparing information between different samples. This technique (ANOVA) would be done if more than two samples (Explorable, n.d.).
There are many types of ANOVA that are commonly used. There is one way ANOVA that has multiple groups but one variable (Explorable n.d.). there is two-wat ANOVA which has multiple groups with two variables and three-way ANOVA is the same except is has three variables (Explorable, n.d.). These techniques can be used in many different scenario arenas. It is a great tool to use when it is mastered.
