The output of the test will provide you with the differences between groups. First, check for significance, which is provided in the chart under “Sig. (2-talied).” If there is significance, look at the Group Statistics box under Mean. This will give you the information you need to state if there is significance between groups. If there is no significance, you still have results that mean something. Write them up in APA format. Follow the example below. APA Write-Up Example An independent t -test was conducted to compare the mean IPV physical victimization scores of male high school students (N=172, M=2.70, SD=3.82) with those of female high school students (N=64, M=2.25, SD=3.67). This comparison was found not statistically significant. The results indicate that boys and girls did not differ in likelihood of being victims of physical violence.
