ESSAYBID ANSWER

ANS: A
Control involves the imposing of rules by the researcher to decrease the possibility of error and thus increase the probability that the study’s findings are an accurate reflection of reality.
Data are collected from the sample, however, the sample is created.
Random sampling does not alone establish an experimental study.
Manipulation is when the researcher makes changes in the treatment received by the subjects.
