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. solid wood king size bed framesWebThe Critical Values for a 90% confidence or alpha = .10 are +/- 1.645.
