Verified step by step guidance

Understand the scientific method: It is a systematic approach used in scientific study to make observations, form hypotheses, conduct experiments, and draw conclusions.

Identify the role of different groups in an experiment: In an experiment, groups are used to test the effect of a variable. These groups are typically divided into control and experimental groups.

Define the control group: This is the group that does not receive the treatment or variable being tested. It serves as a baseline to compare the results of the experimental group.

Define the experimental group: This is the group that receives the treatment or variable being tested. The purpose is to observe the effect of the variable on this group.

Clarify the purpose of the experimental group: The experimental group is crucial for testing the hypothesis. By comparing its results with the control group, researchers can determine the effect of the variable being tested.
