system, which was implemented over a year ago, to see if the automated syst

She is comparing quarterly reports from this past year on volume of patients
zz zz zz zz zz zz zz zz zz zz zz zz zz



who did not show up to their appointments, to the volume of patients of
zz zz zz zz zz zz zz zz zz zz zz zz zz



the previous year, who did not show up to their appointments, to see if the au

tomated system has proven effective. She is considering other variables as s

5.There are two standard treatments for children with ADHD who display

a specific set of characteristics. One treatment is a cognitive behavioral in

zz zz zz zz zz zz zz zz zz zz zz zz zz z



of the children will receive the cognitive behavioral intervention and the other
zz zz zz zz zz zz zz zz zz zz zz zz

atistics to analyze the data to support their decisions for recommendations.
zz zz zz zz zz zz zz zz zz zz zz



Which of the following descriptive statistics could prove the most useful?: The
