When the lines in a graph of the cell means are roughly parallel in factorial ANOVA, we can conclude that:
When the lines in a graph of the cell means are roughly parallel in factorial ANOVA, we can conclude that:
a. Neither the main effect for factor A nor factor B is statistically significant.
b. Main effects for factor A and factor B are statistically significant.
c. The interaction effect of factor A and factor B is statistically significant.
d. The interaction effect of factor A and factor B is not statistically significant.
