WebJul 15, 2024 · The tables following Figure 11.4.1.1 show the critical t-score. If the your calculated F-score is bigger (more extreme) than the critical F-score, then you reject the null hypothesis. If the calculated F-score is to … 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.
WebThe value you calculate from your data is called the F Statistic or F value (without the “critical” part). The F critical value is a specific value you compare your f-value to. In general, if your calculated F value in a test is larger than your F critical value, you can … Example question: Find the critical value for alpha of .05..
