Question
Alfred randomly grouped the participants into two and tested the effects of his new product towards their endurance. His study uses this type of research design:A.CorrelationalB.SurveyC.ExperimentalD.Causal-comparative
Solution
The correct answer is C. Experimental. This is because Alfred is manipulating a variable (the new product) and testing its effects on another variable (the participants' endurance). This is characteristic of an experimental research design, where the researcher has control over and manipulates the independent variable.
