- Acne is a common skin disease that affects most adolescents and can continue into adulthood. A study compared the effectiveness of three acne treatments and a placebo, all in gel form, applied twice daily for 12 weeks. The study's 517 teenage volunteers were randomly assigned to one of the four treatments. Success was assessed as clear or almost clear skin at the end of the 12 week period. The results of the study can be seen in the table below. Using the appropriate statistical test, determine if there is significant evidence that the four treatments perform differently. If so, how do they compare.arrow_forwardThe most important advantage of experiments over observational studies is that.. a confounding cannot happen in experiments. observational studies cannot use random samples. experiments can give better evidence of causation. experiments are usually easier to carry out.
