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.

What decision should be made regarding the null hypothesis?
8. Are the results statistically significant?
9. Give a one sentence conclusion for this study.
10. Name on potential confounding variable for this study.

7. The null hypothesis of the study should be rejected.

8. The results can be considered statistically significant as the p-value is less than 0.05.

9. Children of divorced parents are not as socially well-adjusted as children of parents who are married.

10. Sampling bias may be a problem in the study. It is a bias in which a sample is collected in such a way that some members of the intended population are less likely to be included than others.
