Paper 1 · Research Aptitude
Consider the following two statements and choose the correct option:
- The experimental group is the group of research participants who receive the experimental treatment
- True experiments must have at least one control group, though it is possible to have more than one experimental group
AOnly 1 is true
BOnly 2 is true
CBoth 1 and 2 are true ✓ Correct
DNeither 1 nor 2 is true
Correct answer: (C) Both 1 and 2 are true — Both statements are true, so the answer is that 1 and 2 are both true.
Explanation
★Both statements are true, so the answer is that 1 and 2 are both true.
★The experimental group is indeed the group that receives the experimental treatment, so the first statement is true.
★A true experiment must have at least one control group for comparison, so the second statement is true.
★It is also true that a study may have more than one experimental group receiving different treatments.
★So both the definition of the experimental group and the requirement of a control group are correct.
★Hence both statements are true.
