    A manager wants to test whether two normally distributed and independent populations have equal variances. the appropriate test statistic for this test is a “F-statistics.”

    What is F-statistics?

    An F statistic is a value obtained after performing an ANOVA test or even a regression analysis to determine whether the means of two populations differ significantly.
    Some key features regarding the F-statistics are-
    • It is comparable to a T statistic from the a T-Test; a T-test would then inform you when a single result is statistically significant, whereas a F test would then tell you if a set of variables is statistically significant.
    • When determining whether your total results are significant, you must use the F statistic in conjunction with the p value. Why?
    • A significant result does not imply that all of your variables have been significant.
    • The statistic is simply comparing the cumulative influence of all the variables.
