change your design.

don't need to change your design.

Imagine you are a researcher interested in the effects of marijuana on
beliefs in conspiracy theories. The study involves two groups, to which
people are assigned by chance: Group A takes a pill that contains the
active ingredient in cannabis, THC, while Group B are given a harmless
placebo pill. Neither the people conducting the study nor the participants
know who is getting the drug and who is not. After taking the pill and
completing some filler tasks, participants are given a series of surveys to
complete. One of these theories asks them to indicate the extent to
which they believe in different conspiracy surveys (e.g., a secret group like
the Illuminati controls the world, Obama was not born in the US & is
secretly a Muslim, 9/11 was an inside job, the moon landing was faked).

Expert Solution

Introduction

The experimental method is used by psychologists to study the effects of the independent variable on the dependent variable in a controlled laboratory setting or a field setting. In the experiment, the experimenter divides the participants into two groups namely the control and experimental group. The experimenter administers the independent variable to the experimental group while the control group receives no treatment and based on these groups the researcher conducts the study.
