F critical value in r

WebJul 15, 2024 · One option is to use the Degrees of Freedom that is closest to your sample's Degrees of Freedom. For our example of r (98), that would mean that we would use the Degrees of Freedom of 100 because 98 is closer to 100 than to 90. That would mean that the critical r-value for r (98) would be 0.194604 for a p-value of 0.05. WebThe point of intersection is your critical F-ratio. 3. If your obtained value of F is equal to or larger than this critical F-value, then your result is significant at that level of probability. An example: I obtain an F ratio of 3.96 with (2, 24) degrees of freedom. I go along 2 columns and down 24 rows. The critical value of F is 3.40.
