The purpose of this PowerPoint is to present strategies to aid students at the high school and introductory college levels to:. Design experiments. Write procedures. Construct tables and graphs. Generate ideas. Researcher manipulates the independent variable (usually to create groups) and then compares the groups in terms of their scores on the dependent variable (outcome measure) while keeping all other variables constant through direct experimental control or randomization- If score on the dependent variable are different then the researcher can conclude that the difference was due to the difference between groups and no other cause (and the experiment will have internal validity) .
