If you are part of a group that is testing a new drug 25% of the control group given placebo would you conclud?

And 46 % of the experimental group given the drug reported an improvement in their symptoms. WOuld you conclude that this is an effective drug? What other variable might be present in the study participants that might have influenced which patients benefited from the new Drug?|||Among other things, it depends a lot on sample size. If your 25% is one in a control group of four, that could pretty well represent anything. 1000 out of 4000 you might take to the bank.


As you mentioned, there are usually a lot of confounding variables, but you have to look more into the study design and any known differences in the control group and the treatment group to comment on them.
