MANOVA, or Multivariate Analysis of Variance, is a statistical technique used to simultaneously test the equality of means of several dependent variables and determine if the differences are significant between two or more groups. It is a more powerful alternative to traditional ANOVA methods when multiple response variables are present, and can help to identify complex relationships between variables and groups.

According to Pillai (1987), MANOVA is useful in situations where there are multiple dependent variables and the researcher wants to determine if there is a significant difference between groups on these variables. It allows for the examination of the relationship between the independent variables and the dependent variables as a whole, rather than just looking at each dependent variable individually.

Tabachnick and Fidell (2001) suggest that MANOVA is useful for research in fields such as psychology, education, and the social sciences, where multiple dependent variables are often used to measure different aspects of a concept. For example, a study may use multiple measures of aggression (such as verbal aggression and physical aggression) to determine the effectiveness of a aggression intervention.

Hair et al. (2010) emphasize the importance of using MANOVA in situations where the dependent variables are correlated, as it accounts for this correlation and can provide more accurate results. Field and Hole (2013) also note that MANOVA can be used to determine the presence of interactions between the independent variables and dependent variables, which can provide insight into the nature of the relationships between these variables.

Kachigan (2016) discusses the use of MANOVA in analyzing data from experiments with more than one independent variable. He explains that MANOVA can be used to determine if there are significant differences between the groups on the dependent variables and if these differences can be attributed to the independent variables.

Tabachnick and Fidell (2017) discuss the use of MANOVA in analyzing data from experiments with more than one dependent variable and multiple independent variables. They note that MANOVA can be used to determine if there are significant differences between the groups on the dependent variables and if these differences can be attributed to the independent variables, as well as to examine the presence of interactions between the independent variables and dependent variables.

In summary, MANOVA is a useful statistical technique to simultaneously test the equality of means of several dependent variables and determine if the differences are significant between two or more groups. It is particularly useful in fields such as psychology, education, and the social sciences, and can be used to analyze data from experiments with more than one independent variable and multiple dependent variables. It could also be used to determine the presence of interactions between these variables.
