The f-statistics can be represented as the following: f = 32.325 at the degree of freedom as 3, 196. The next step will be to find out the critical value of F-statistics at the level of significance as 0.05 with the degree of freedom as ...
WebUse this calculator to compute a two-tailed P value from any Z score, T score, F statistic, correlation coefficient (R), or chi-square value. Once you have obtained one of these statistics (from a publication or even another program) the P value helps interpret its statistical significance.
