Quizplus · Accepted Answer

An experimental study involves manipulating a variable in a test group and comparing the responses to a control group. In this type of study, the researcher has control over the independent variable and can manipulate it to see the effect it has on the dependent variable. The control group is used as a baseline to compare the experimental group's results, allowing researchers to make cause-and-effect conclusions about the relationship between the independent and dependent variables.
