• Confounding variable

Sample does not adequately represent population

• Population

• Sample

• Representative sample

• Bias sample

Group exposed to the IV

• Experimental group

• Controlled experiment

• Control group

• Control condition

Which variable is one that is considered to have an affect on the DV so it needs to be held constant?

• Independent variable

• Confounding variable

• Controlled variable

• Dependent variable

Each participant is in both the experimental and control group

• Between subjects

• Within subjects

• Mixed design

An ________ variable is any variable that's not the independent variable but may affect the results (dependent variable) of the research.
