20. ERAU wants to know if it is better for Instructor Pilots to give flight students feedback in the airplaneimmediately after each maneuver rather than to wait till they are on the ground and debriefing. Six student pilots areselected. Each student receives immediate feedback on half of their flights and receives delayed (after landing)feedback on the other half of their flights.

She randomly assigns 52 people to a treatment group and 52 to a placebo group. The treatment group receives a medication over a period of three months and the placebo group receives a placebo over the same time frame. At the end of three months the patients' symptoms are evaluated. experiment observational study

Brand equity of one brand for one respondent is the difference of branded score and unbranded score of that brand evaluated by the respondent. The marketing researcher would like to find out whether brands A and B have brand equity, in other words, whether the evaluation of brand A (B) is different when consumers can see the brand name vs. when they cannot see the brand name.
