Highlights

•    An Analysis of Variance (ANOVA) is a commonly used statistical tool to compare means of dependent variables across multiple populations.
•    Choosing the appropriate ANOVA depends on the type of independent variable (continuous or categorical) and the number of independent variables.
•    ANOVAs only indicate whether a difference exists between groups and not where the difference exists.

An Analysis of Variance (ANOVA) is a common statistical analysis method used in all disciplines of research. The development of statistical software has simplified the process of calculating ANOVAs. Given the ease of access however, choosing the appropriate type of ANOVA can be difficult based on how the study is designed. This OE Original provides a guide to understanding the family of ANOVAs.
