Analysis of variance (ANOVA) is probably the most frequently applied of all
statistical analyses. ANOVA is extensively applied in many fields of research, such as
anthropology, biology, commerce, economics, education, industry, medicine, political
science, psychology, sociology, and etc. One reason for the popularity of ANOVA is its
suitability for many different types of study design. ANOVA places no restriction on the
number of groups or conditions that may be compared. Another reason of the frequency
of ANOVA applications is that it is suitable for most effect comparisons by testing for
differences between means [1].
