WebAnalysis of variance (ANOVA) is a set of statistical models and the estimate processes that go with them that are used to assess the differences between means. Ronald Fisher, a statistician, invented ANOVA. WebFactor structure. Exploratory factor analysis was used according to different factors frequently. Ultimately, the 3-factor model was the best result of a simple pattern of loadings based on eigenvalues >1, as well as a total of 71% of variance was explained by the 3-factors model. The Kaiser–Meyer–Olkin index was 0.88.
