WebThe value you originate from your statistics is known as the F-value or F-Statistic. The F-critical value is a specific value to which your F-value is compared. You can reject the null hypothesis if your calculated F-value in a test is greater than your F-critical value. In an F-Test, however, the statistic is only one measure of significance. WebThe critical value for a one-tailed or two-tailed test can be computed using the confidence interval. Suppose a confidence interval of 95% has been specified for conducting a hypothesis test. The critical value can be determined as follows: Step 1: Subtract the confidence level from 100%. 100% - 95% = 5%.
