There are 2 scientific studies testing the effect of a drug on the immune system of AIDS patients. Both studies use the scientific method and are published in scientific
journals. In each study scientists give the drug to one group of people and a placebo
to a second group of people. Both studies measure how many times the patients get
sick over the next year. One study has high variance in the dependent variable
(number of times a person was sick). One study has low variance in the dependent
variable. Which study has statically significant results?
