Inferential statistics allow conclusions about a population from sample data. ANOVA (Analysis of Variance) is used to test whether the means of three or more groups differ significantly, by comparing between-group variation to within-group variation with the F-statistic. This makes it the go-to method for assessing population mean differences when you have multiple groups. Descriptive statistics simply summarize data, not draw population inferences; correlation describes the relationship between two variables rather than differences in group means; a t-test also infers differences but only between two groups, whereas ANOVA extends this to three or more groups.
