Quizplus · Accepted Answer

In order to test the effects of Echinacea on reducing cold symptoms, a control group that is similar to the experimental group in all aspects except for the variable being tested is needed. Therefore, the appropriate control group would be 100 sick people given tablets similar to Echinacea but with no herb. This would allow for a comparison of the effectiveness of Echinacea in reducing cold symptoms, as any changes observed in the experimental group can be attributed to the Echinacea, while changes observed in the control group can be attributed to factors other than the herb.
