What are the difference groups in an experimental study? Type your answer. __

## Step 1<br />In an experimental study, the researcher manipulates one or more factors (independent variables) to observe the effect on another factor (dependent variable). The participants are randomly assigned to different groups to ensure that the groups are comparable and that the results are not due to pre-existing differences between the participants.<br /><br />## Step 2<br />The first group is the Experimental Group. This group is exposed to the independent variable or the treatment that is being tested. The researcher manipulates this group to observe the effect of the independent variable on the dependent variable.<br /><br />## Step 3<br />The second group is the Control Group. This group is not exposed to the independent variable or the treatment. It serves as a baseline to compare the results of the experimental group. The control group helps to ensure that any changes in the dependent variable are due to the independent variable and not other factors.<br /><br />## Step 4<br />The third group is the Comparison Group. This group is similar to the control group, but it receives a different treatment or condition than the experimental group. This group helps to ensure that the results are not due to the passage of time or other factors, but specifically due to the independent variable.
