ANOVA, or Analysis of Variance, is a statistical method used to compare the means of three or more groups to determine if there are significant differences between them. It works by analyzing the variance within each group and the variance between the groups. ANOVA tests whether the observed differences among group means are greater than what could be expected by chance. There are different types of ANOVA, including one-way ANOVA (which compares one independent variable across multiple groups) and two-way ANOVA (which compares two independent variables and their interaction effects). ANOVA is widely used in experimental research, particularly in fields like psychology, biology, and marketing, to test hypotheses about group differences. If the ANOVA indicates significant differences, further tests like post-hoc comparisons are used to identify which groups differ. This is an advanced or PG Level ANOVA MCQ Quiz with Answer Key.
