to a visual depiction of the means. Figure 15.20 presents the results of
the first set of simple effects comparing levels of toytype .Wearethus
comparing the amount of time the children spent playing with hands-on
toys versus the time they spent playing with pretend toys. This compar-
ison is performed separately for females and then for males, first for the
yellow toys and then for the blue toys; with respect to Figure 15.3, we are
determining if each line significantly slants with respect to the x axis.
Our results indicate that only one pair of means differed significantly.
Therewasadifferenceinplaytimebetweenthe hands-on and pretend
toys for gender 1 (girls) for color 1 (yellow). Examining the comparisons
one by one in Figure 15.3, we can derive the following summary:
For the yellow toys, girls played with pretend toys more than they
played with the hands-on toys; boys played a comparable amount of
time with both types of toys.
