Question
Research in which attempts are made to establish causality by drawing on naturally existing variations rather than active manipulation of the independent variable would most typically use a____________ design. A. true experimental B. developmental C. quasi-experimental D. non-experimental
Solution
The correct answer is C. quasi-experimental. This type of research design is used when the researcher wants to establish a cause-and-effect relationship but cannot control all the variables. In a quasi-experimental design, the researcher takes advantage of naturally occurring differences or changes (like age or time of year) to create groups that are compared. This is different from a true experimental design, where the researcher has full control over all variables and can randomly assign participants to groups. Developmental and non-experimental designs do not typically seek to establish causality.
