A researcher tests out a classroom intervention to enhance children's social interaction. Some children receive the intervention, whereas others do not. The researcher counts the positive interactions between children across a period of two years. Children who received the intervention are found to be more positive in these interactions. Which one of the following conclusions is most justified?
◦ Because the intervention caused children to interact positively with peers, this method should be adopted by the entire school district.
◦ The intervention may have caused children to interact positively. However, other factors - such as parent involvement in the study - may also explain the difference in behavior.
◦ Because only some children received the intervention, we can't draw any conclusions about its effectiveness for children in general.
◦ Two variables - the intervention and social interaction - are related. There is no basis for speculating that one has caused the other.
