An investigator is studying the effect of two physical fitness programs (M and N) on boys and girls. The experimental design is a 2 x 2 factorial design. The results of the investigation might be one of the following four conditions. condition (a) condition (b) M N M N Boys X = 50 X = 60 Boys X = 50 X = 60 Girls X = 60 X = 50 Girls X = 40 X = 60 condition (c) condition (d) M N M N Boys X = 50 X = 40 None of these conditions Girls X = 60 X = 50 . Which condition shows neither an interaction effect nor a main effect?
