In an experiment, having more control groups than experimental groups is not a strict requirement; rather, it depends on the specific research question and design. Control groups serve as a baseline to compare the effects of the experimental conditions, so having multiple control groups can help account for variability and confounding factors. However, too many control groups may complicate the analysis and interpretation of results. The key is to balance the number of control and experimental groups to effectively address the research hypothesis while maintaining clarity in the findings.

True
To help you conclude that no uncontrolled factors significantly influenced your results. To help you determine that your experimental results are valid To help control for factors that aren't being tested but might affect results

it is the groups in experiment
experimental and control
Experiments typically use control groups. One group of people are manipulated and measured, while the control group just stays as they are. The control group is measured against the manipulated group to see what changes.
In a controlled experiment, there are two groups. The control group is a group that nothing happens to. The experimental group is the group that you subject to the variable with which you are experimenting. At the end of the experiment, you test the differences between the control group, for whom nothing happened, and the experimental group, which received the variable. The difference (or similarities) between the two groups is how your results are measured.A control group is the group used for comparison in an experiment. One group receives the treatment that is being tested by the experiment; another group (the control group) has the exact same controlled environment, but does not receive this treatment. The effectiveness of the treatment can then be established by comparison with the control group.
Control
To make an experiment more accurate, you can increase the sample size to reduce the effect of outliers, use control groups to isolate the variable being tested, ensure measurements are precise and consistent, and repeat the experiment multiple times to verify results.
True
You need a control group and an experimental group.
The two groups in a controlled experiment are the experimental group, which receives the treatment being tested, and the control group, which does not receive the treatment and serves as a baseline for comparison.
Variables
The purpose was to control lands and large groups of people through authoritarian rule.
