Question 1:

Which of the following is true about control groups in an experiment?

A) Control groups receive the experimental treatment.
B) Control groups are not necessary in experiments.
C) Control groups provide a baseline for comparison.
D) Control groups are the same as experimental groups.

Show Answer

Explanation: The correct answer is C) Control groups provide a baseline for comparison. Control groups are a crucial part of experimental design. They do not receive the experimental treatment but serve as a baseline to compare the effects of the treatment in the experimental group. By comparing the control group to the experimental group, researchers can determine the specific impact of the treatment being tested.

Question 2:

Which of the following is true about experimental groups in an experiment?

A) Experimental groups do not receive any treatment.
B) Experimental groups are not necessary in experiments.
C) Experimental groups provide a baseline for comparison.
D) Experimental groups receive the experimental treatment.

Show Answer

Explanation: The correct answer is D) Experimental groups receive the experimental treatment. Experimental groups are the group(s) in an experiment that receive the specific treatment being tested or manipulated. The purpose of the experimental group is to observe and measure the effects of the treatment, allowing researchers to draw conclusions about its impact.

Question 3:

Which of the following is true about control groups and experimental groups?

A) Control groups and experimental groups receive the same treatment.
B) Control groups and experimental groups are not necessary in experiments.
C) Control groups and experimental groups are identical.
D) Control groups and experimental groups are different.

Show Answer

Explanation: The correct answer is D) Control groups and experimental groups are different. Control groups and experimental groups are distinct and serve different purposes in an experiment. Control groups do not receive the experimental treatment and provide a baseline for comparison, while experimental groups receive the specific treatment being tested. This comparison allows researchers to determine the effect of the treatment by assessing any differences between the control and experimental groups.

Question 4:

Which of the following is an example of a control group in an experiment?

A) Participants who receive a new medication.
B) Participants who receive a placebo.
C) Participants who are not involved in the experiment.
D) Participants who are randomly assigned to groups.

Show Answer

Explanation: The correct answer is B) Participants who receive a placebo. In this scenario, the control group consists of participants who receive a placebo, which is an inactive substance or treatment that has no therapeutic effect. The control group allows researchers to compare the effects of the active treatment in the experimental group to the effects observed in the control group receiving the placebo.

Question 5:

Which of the following is an example of an experimental group in an experiment?

A) Participants who are not involved in the experiment.
B) Participants who receive a new intervention.
C) Participants who receive a placebo.
D) Participants who are randomly assigned to groups.

Show Answer

Explanation: The correct answer is B) Participants who receive a new intervention. In this scenario, the experimental group consists of participants who receive the specific treatment or intervention being tested in the experiment. The purpose of the experimental group is to observe and measure the effects of the treatment, allowing researchers to draw conclusions about its impact.
