It can get confusing to know the difference between ANOVA and MANOVA. ANOVA stands for Analysis of Variance while MANOVA stands for multivariate analysis. These two are different from each other. MANOVA can be used more during experimentation because some of the independent variables that are used in the experiment are manipulated.
ANOVA can also be used for experiments but only for single experiments with more natural variables. The design of the MANOVA may be more effective but it is also more complicated than the ANOVA. When using MANOVA, make sure that the dependent variables are not related to each other otherwise, there may be some issues that will appear later on.
