Answer 2

Answer:

To assist you in determining the validity of your experimental data and to help account for variables that aren't tested but could influence outcomes.

Explanation:

• True experimental designs must include control groups as an essential component.
• Researchers can confirm that study outcomes are attributable to the modification of independent variables (IVs) rather than unrelated variables when control groups are present.
• By using controls, the experimenter can reduce the impact of variables other than the one being investigated.
• This is how we can be sure an experiment is testing what it says it is testing.
• Controls are required for any type of experimental testing, regardless of the topic matter, and this goes beyond science.
• In general discussions of observational research, the potential of utilising more than one control group has frequently been briefly noted, and many observational studies have employed two control groups.
