Question

Ii. experimental design practice advertisements for an herbal product, ginseng, claim that it promotes endurance. how would you design an experiment to verify this claim?

Answer 1

Experimental design to test the hypothesis:

Recognition that an experiment can be done to test the claim (versus simply reading the label of the product). Identification of what variable is manipulated (independent variable is ginseng versus something else).

Identification of what variable is measured (dependent variable is endurance versus something else). Description of how dependent variable is measured (e.g. how far subject run will be measure of endurance).

The realization that there is one other variable that must be held constant. Understanding of the placebo effect (subjects do not know if they were given ginseng or a sugar pill)

Realization that there are many variables that must be held constant (versus only one or no mention). Understanding that the larger the sample size or number of subjects, the better the data.
