Answer 3

What do you think? Is the medicine effective?

Answer 4

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

Answer 5

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?

Answer 6

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

Answer 7

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?
