An independent variable is the potential stimulus or cause, usually directly manipulated by the experimenter, so it could also be called a manipulative variable.
A dependent variable is the response or measure of results.
Indicate the independent variable and dependent variable:
A research psychologist, working in a federal prison, is asked to assess the effectiveness of a new life skills program in promoting problem-solving skills. From a pool of 70 inmate volunteers, the psychologist randomly assigns 45 inmates to three
groups. Group A receives life skills training for 2 hours every day for 12 weeks. Group B meet at the same time but plan all their own activities. Group C takes part in the regular prison program. At the end of 12 weeks, all three groups are assessed
on their ability to solve personal & interpersonal problems by responding in writing to a number of "problem scenarios"presented to them.
