ABSTRACT
A significant difference is found among the three means for the pre-, post-and delayed-post-tests, (Time in the analysis) F=22.81; df2, 16; p<0.001 suggesting there may be a possible trend in the data. These means should be plotted but with only three measurement points in time it probably would not be worth examining the data for trends using polynomial terms. Finally, group by repeated measures interaction, sex*time, is significant, F=12.60; df=2, 16; p<0.001. This indicates that male and female vocabulary scores differ depending upon the measurement occasion. Plots of the simple effects that is the effects of one variable at individual levels of the other variable, (for example, a plot of mean vocabulary scores, Y-axis against measurement occasion, X-axis for males and females separately) are likely to be informative.
