Document Summary

New: homosexuals: honesty, large sample and many users to fill it. In order to generalize from the sample to the population, the sample must be representative of the population: sample must be a mini version of the population, mini version done through the most basic form: random. ): variable that the experimenters manipulate to see if it has an effect on behaviour cause. ): the behaviour that is being measured to see if the independent variable has an effect effect. Memory scores are dependant upon independent variable so amount of alcohol is iv and memory is dv. You cant hypothesize the theory, because you cant compare them to anything, and you don"t know whether the sober subjects" scores so we need a control group. You want all of them to be equal in expectations. The control and experimental groups must be similar in every way, except for the independent variable.
