In a study of factors that might affect memory, research participants were assigned to drink either an alcoholic or a nonalcohol
ic beverage prior to completing a memory test. Those who drank the nonalcoholic beverage were assigned to the group. A) survey B) control C) experimental D) correlational
Survey is when you ask questions to a group of people. Has nothing to do in this case. Correlational does not exist but correlation means the association between two groups.
In an experiment, you apply a treatment, or a conditions that differentiates groups and measure an outcome . In this case the treatment is drinking alcohol to measure memory. The group that receives the treatment is the experimental group and the one that not receives the treatment is the control because, we are comparing or controlling alcohol consumption in this group to measure differences in memory with the experimental group.
