• the type of experiment is used by psychologists

The one variable you change and test in an experiment to see if it has an effect

• Controlled variables (constants)

• Dependent variable (responding variable)

• Independent variable (manipulated variable)

• Control group

Using a observational design a psychologist investigate the effects of sleep quality on decision making when driving using a simulator. Identify the pre-existing variable.

• Decision making

• Simulator driving ability

• Sleep quality

The main purpose of focus group is......
