A researcher was interested in whether there were differences in the level of activity in children who had been diagnosed with ADHA depending on whether they had received no treatment, were on Ritalin, or were in a behavior management program. He recruited 90 children with ADHD to participate, and randomly assigned each child to one of the three groups. The number of classroom disturbances during a 1 hour period was measured for each child. Which statistical test would be best to determine if there is a significant difference between groups? one-sample t-test dependent samples t-test independent samples t-test ANOVA
