I've included my explanation in the word document.
Independent variable: participants (children and adolescents)
Dependent variable: performance index reflecting addictive thinking and substance abuse.
The null hypothesis: there is no significant difference for the mean performance index between participants without stimulant medications and participants with stimulant medications.
The expert tests stimulant medications.
