Statistical Analyses and Interpretation Independent t-test The hypothesis in this study was that: H0: ADD-like behavior is the same in males and females. H1: The mean ADD-like behavior scores between males and females are different. While conducting the independent t-test, it is assumed that each data point in the sample is independent, the data in each of the two populations are normally distributed, and that the two populations have equal variances. In this study’s t-test analysis, it was identified that there was a statistically significant (t(214) = .261, p < .001) difference in ADD-like behaviors between males and females. This led to the rejection of the null hypothesis; ADD-like behavior is the same in males and females. Males (M= 56.09, SD = 10.00) had a higher ADD-like behavior score compared to females (M = 49.09, SD = 9.722). The results of the t-test showed without doubt that males differed significantly in ADD-like behaviors compared to females with males showing more ADD-like behaviors. Another important finding from the t-test analyses was that there was no statistically significant difference (t(214) =3.559, p > .001) in ADD-like behaviors for persons who showed social adjustment problems in 9th Grade compared to those who did not have social adjustment problems. In the same manner, there was no statistically significant difference (t(214) = 3.228, p > .001) between those who had dropped out of high school and those who had not. It is therefore clear that having or lack of social adjustment problems as well as dropping/or not dropping out
