Parallel lines (neither crossed nor converging) in a line graph representing cell means from a factorial ANOVA suggest that there is no significant interaction between the factors. This is because the effects of one factor are consistent across the levels of the other factor, indicating that the factors do not interact to affect the dependent variable.
