Some have claimed that children of divorced parents are not as socially well-adjusted as children of parents who are married. To test this idea, Dr. Curious set up a study with two groups. One group consists of 100 children who have divorced parents. The other group consists of 100 children who have married parents. Each child in the study is asked to complete the Social Adjustment Scale for Children (SASC). Higher scores on the scale indicate better social adjustment. The results indicate a mean difference of 10 points on the SASC between the two groups. Alpha (significance level) was set at .05 and the results had a p=.04.
