Hello everyone here. We have a question asking which one of the following is incorrectly matched regarding the control and experimental group and an experiment. A control group remains unaffected by variable. The control group receives a standard or fake treatment or no treatment, so they do remain unaffected by the variable. So A. Is correct. B Control group receives a placebo treatment. That is correct. C experimental group receives the actual treatment that is correct. D experimental group eliminates the alternative hypothesis. This is incorrect. So our answer here is deep. Experimental group eliminates the alternative hypothesis. The experimental group is the group that receives the treatment. Thank you for watching. Bye.
