Here is an ANOVA summary table for a 2-way fixed-effects balanced design. Using =FINV () in Excel, find the critical values for each hypothesis test at both the a = 0.05 and a = 0.01 significance levels. Source SS df MS F F0.05, dfi,df2 F0.01, df, df2 A 3771.3 4 942.825 1.628 B 7133.3 5 1426.66 2.464 A B 21381 20 1069.05 1.846 Error TOTAL 173700 205985.6 300 329 579 Round to four decimal points. Finally, what was the sample size for each cell in this 2-factor design? n = Hint: Add 1 to the total degrees of freedom to compute the overall total number of data values in the table. Next, add 1 to the df for A & B to compute the actual number of groups in each row category (A) & column category (B). Now to compute the sample size simply take the overall total (df+1) divided by the PRODUCT of the number of row and column groups. This will produce "n" or the number of samples in each grouping.
