WebCalculate the ANOVA table with degrees of freedom (df) and F value as shown below. Determine the critical value. Remember, F(critical) is from the F distribution table. Finally, Draw the statistical conclusion. If Fcalc< Fcritica,l fail to reject the null hypothesis, and if Fcalc > Fcritical, reject the null hypothesis. WebDetails on how the SS and DF are computed can be found in Maxwell and Delaney (1). Table 12.2 on page 576 explains the ANOVA table for repeated measures in both factors. But note they use the term "A x B x S" where Prism says "Residual". Table 12.16 on page 595 explains the ANOVA table for two way ANOVA with repeated measures in one factor.

WebFor Welch's ANOVA, Minitab uses the degrees of freedom for the denominator to calculate the probability of obtaining an F value that is at least as extreme as the observed F value. Interpretation. Minitab uses the F-value to calculate the p-value. Typically, you should assess the p-value because it is easier to interpret.
WebF-distributions require both a numerator and denominator degrees of freedom (DF) to define its shape. For example, F (3,2) indicates that the F-distribution has 3 numerator and 2 denominator degrees of freedom..
