Question 5

A researcher was interested in whether divorce and remarriage influence the extent to which children are sociable. At a nearby school, the researcher classified 5th-graders into one of three groups: intact parents (no divorce), divorced (single-parent families), and remarried parents. The researcher interviewed the 5th-graders and rated their sociability, and also asked them to complete a questionnaire that assessed their level of comfort of different social situations.
-What type of experimental design did this researcher use?

Accepted Answer

A natural
