Probability and statistics help.. will fan and give medal. Andria is conducting an experiment to determine whether a new medication is effective in reducing swelling. She gets 1,000 volunteers with swelling and divides them into 2 groups. The control group does not receive any medication; the treatment group receives the medication. The patients in the treatment group show reduced signs of swelling. What can Andria conclude from this experiment?

i don't think so. since the control group didn't receive anything she doesn't really have anything to compare it to.

Precisely. Great observation! Yes, the group that took the medicine had reduced swelling. But we're not told anything about the control group - maybe their swelling stayed the same, maybe it got worse, maybe it got better - we don't know. So what can Adriana conclude from the experiment?

That her medication was not effective or we can't tell

If we don't know anything about how the control group got along, can Adriana make any conclusions at all about the effectiveness of the medicine?
