All groups should be equal except for the independent variable. Instead of only giving an alcoholic drink of 2oz and 4oz, and no drink to the 0oz, ALL groups should have something to drink.

Waiting List Control Group • a control group where subjects are not yet receiving treatments or therapy, but eventually will, after the study is over. • Other group receives the therapy immediately; or a new type of therapy vs. an old therapy. 3. Yoked Control Group • used when subjects in the experimental group participate for varying amounts of time or experience different things in the study. Each subject in the control group is yoked (matched) to a subject in the experimental group so that, for the groups as a whole, the time and type of event are kept constant. • you are trying to control for procedure.
