Quizplus · Accepted Answer

To study the relation between early experiences and later outcomes, a longitudinal design is necessary. This design involves monitoring the same individuals over an extended period of time. Therefore, using a parent-questionnaire to monitor language development at age 12 months and then measuring developmental outcomes at age 3 years would require a longitudinal design. A quasi-experiment design involves manipulating a variable, which is not relevant to this question. A parent diary may provide useful information, but it does not necessarily involve monitoring the same individuals over an extended period of time. Cluster analysis is a statistical method used to group similar individuals or variables, but it is not necessary for this study.
