Chi-square test of independence results.

Feature	Chi square value	p-Value	Cramer’s*
Attention deficit	43.14	0.00000	0.44
Inattentiveness	50.45	0.00000	0.47
Impulsivity	6.27	0.01225	0.17
Sustained attention	3.87	0.04920	0.13
Vigilance	12.33	0.00045	0.23
Gender	6.00	0.01430	0.16

^*Attention deficit, inattentiveness, impulsivity, sustained attention, and vigilance was all significant. Gender was also found to be significant. Cramer, greater than 0.30, in Inattentiveness (0.47 Cramer’s *), Attention Deficit (0.43 Cramer’s *), and Vigilance (0.23 Cramer’s *) are significant (medium relation if Cramer >0.30 with df = 1). Significant differences indicate that the samples come from different populations. Consequently, it can be inferred that the significant variables predict the group the participant belongs to.
