The F ratio, used in ANOVA (Analysis of Variance), can be applied to post-facto data to compare the variances between groups and determine if there are any statistically significant differences among the means. Post-facto research involves analyzing data after the events have occurred, and the F ratio can still be a useful statistical tool in such analyses.
