Researchers studying meditation contacted over 1,000 randomly selected adults in 10 nations. The results showed that those who meditated on a regular basis were less likely to suffer from stress than adults who meditate less regularly or not at all. Can we conclude that meditating caused the lower stress? Why?

(A) Yes, because the sample size was large

(B) Yes, because the adults were randomly selected

(C) Yes, because the adults were randomly assigned

(D) Not necessarily, because the sample size was too small

(E) Not necessarily, because this wasn't an experiment

UPDATE: CORRECT ANSWER IS E

(E) Not necessarily, because this wasn't an experiment

Step-by-step explanation:

As much as the results would suggest that the fast-paced music was responsible for the faster finishing time, this conclusion cannot be authoritatively made because this was not technically an experiment but rather a test to satisfy curiosity.

An experiment is planned and is scientific. It has more stringent requirements that ensure causation that Roshanda did not meet before she engaged in this trial so we cannot say for a fact that her findings are objective.

C. yes, the students were randomly assigned to treatment and control groups.
