AP PSYCHOLOGY

Detailed explanation-1: -A control in a scientific experiment is something used as a standard for comparison to check the results of an experiment. Controls are important because they provide a baseline for comparison of the dependent variable in the experiment.

Detailed explanation-2: -A control variable is any variable that’s held constant in a research study. It’s not a variable of interest in the study, but it’s controlled because it could influence the outcomes.

Detailed explanation-3: -A part of the experiment that is not being tested and is used for comparison of the experimental results. A control group should be used when conducting an experiment. This group receives the same attention as the test groups, however, it will not be influenced by the variable the other groups are testing.

Detailed explanation-4: -Control variables are held constant or measured throughout a study for both control and experimental groups, while an independent variable varies between control and experimental groups.

Detailed explanation-5: -Controlled experiments require control groups. Control groups allow you to test a comparable treatment, no treatment, or a fake treatment (e.g., a placebo to control for a placebo effect), and compare the outcome with your experimental treatment.
