Question 1

Correct Answer:

Verified

A factorial study compares the effectiveness of two allergy medications by measuring symptoms immediately before taking the medication,30 minutes after the medication,and 3 hours after the medication.Half of the participants take one of the medications and the rest take the second medication.Which statement accurately describes this study?

Question 2

Correct Answer:

Verified

A two-factor study compares the effectiveness of two different treatments (factor 1)by measuring performance before treatment,immediately after treatment,and 3 months after treatment (factor 2)for each participant.Half of the participants are randomly assigned to treatment A and half to treatment B.The results from this study should be evaluated with an independent-measures two-factor analysis of variance.
