Analysis of Variance (ANOVA)

Analysis of Variance (ANOVA) is a statistical method used to compare the means of three or more groups to see if there are significant differences among them. Instead of checking each pair of groups individually, ANOVA evaluates all at once, helping to determine if at least one group is different. It helps researchers understand if variations in data are due to actual differences between groups or just random chance. ANOVA is commonly used in experiments and studies to make informed decisions based on the data collected.
