When calculating the between subjects factorial ANOVA, T is the total _____.
 
  a. of the squared scores
  b. of the number of participants in the rows
  c. of the marginals
  d. number of levels of the two variables combined

Question 2

When all three F ratios have the same degrees of freedom (as they do in a 2 2 between subjects factorial design), _____.
 
  a. the interaction is always significant
  b. there is an extra step necessary in the ANOVA
  c. they will all have the same value of obtained F
  d. they can all be compared to the same critical value of F

Answer to Question 1

C
T is obtained by adding all the scores. Because the scores added across the rows and down the columns of the totals summary table produce marginals, T is also the sum of the marginals.

Answer to Question 2

D
The critical value of F is determined by consulting the table under the degrees of freedom associated with the numerator and denominator of the F ratio. When the degrees of freedom are the same for all values of the calculated F,all values of the critical F will also be the same.
