Web23 Jun 2024 · The below-mentioned formula represents one-way Anova test statistics. The result of the ANOVA formula, the F statistic (also called the F-ratio), allows for the analysis of multiple groups of data to determine the variability between samples and within samples. The formula for one-way ANOVA test can be written like this:
