When is the independent variable statistically significant?	An independent variable is statistically significant when the calculated F ratio is greater than, or equal to, a critical F ratio.
How is the mean square calculated	sum of squares divided by the degrees of freedom
A statistically signifcant F ratio indicates...	that levels of the independent variable difer by more than chance
