Question: Teacher perceptions of children with cancer. Liang, Chiang, Chien, and Yeh (2007) tested whether teachers for children with cancer (case) perceived these children similarly to a group of healthy children (control). They measured a variety of social factors, including social withdrawal, somatic complaints, and other social problems. The following table summarizes many of their results using the related-samples t test.
(a) Is this a repeated-measures design or a matched-pairs design?
(b) Interpret the results displayed in the table. Do teachers perceive children with cancer as having more social problems than their peers?
