Question

Quizplus · Accepted Answer

Experimental designs are considered the most rigorous because they involve manipulating an independent variable to observe its effect on a dependent variable. This allows for the establishment of cause-and-effect relationships. Random assignment to control and intervention groups is typically used to ensure that the two groups are comparable at the start of the study. Experimental designs are commonly used in the social sciences, although they may not always be feasible or ethical. The comparison and control groups must be as equivalent as possible to ensure that any observed differences in outcome are due to the manipulation of the independent variable rather than other factors.
