# What does a higher F-statistic mean?

If the value is much larger than $1$ then the variance of the first population is greater than the second.
$F = {s}_{1}^{2} / {s}_{2}^{2}$
If the value of the statistic is $1$ then the two variances are equal. If the value is much larger than $1$ then the variance of the first population is greater than the second.
