Paper 1 · Research Aptitude
Consider the following statements about the control group. Which of them are correct?
- True experiments must have a control group
- The control group is a group of research participants who resemble the experimental group but do not receive the experimental treatment
- The control group provides reliable baseline data to which the experimental results can be compared
AOnly 1 and 2
BOnly 2 and 3
COnly 1 and 3
DAll of the above ✓ Correct
Correct answer: (D) All of the above — All three statements about the control group are correct, so the answer is all of the above.
Explanation
★All three statements about the control group are correct, so the answer is all of the above.
★A true experiment must have a control group for comparison.
★The control group resembles the experimental group but does not receive the experimental treatment.
★So it stays as it was and provides a reliable baseline.
★The experimental results are then compared against this baseline to judge the treatment's effect.
★Since each statement is correct, all three together are right.
