A)The number of main effects that need to be examined
B)The number of interactions that need to be examined
C)The number of participants needed
D)The number of researchers needed

The number of researchers needed does not inherently change based on the design complexity (2 × 3 × 4 mixed factorial design versus a 2 × 4 independent-groups factorial design). The changes in design affect the statistical analysis (main effects, interactions) and potentially the number of participants, but not the quantity of researchers required.
