Analysis of Variance
Analysis of Variance (ANOVA) is a statistical method used to compare the means of three or more groups to see if at least one group differs significantly from the others. Instead of looking at individual comparisons, ANOVA assesses variations within and between groups simultaneously. This technique helps researchers determine if the differences among group averages are likely due to chance or if they reflect true differences in the populations being studied, making it valuable in various fields, such as medicine, psychology, and social sciences for understanding the effects of different factors or treatments.

Analysis of variance (ANOVA) is a statistical method used to compare the means of three or more groups to determine if there are significant differences among them. Instead of comparing each pair of groups individually, ANOVA tests whether at least one group mean is different from the others in one go. It's useful in various fields, from science to business, helping researchers identify factors that affect outcomes, such as testing different teaching methods or product designs. If ANOVA indicates significant differences, further analysis can pinpoint which specific groups differ.
