Question

Which of the following is not true of a laboratory experiment

a. Researcher randomly assigns participants into various treatment conditions

b. The researcher has a low degree of control over the conduct of the study

c. The experimenter designs the study to test how certain aspects of an actual environment affect behavior

d. A laboratory setting must mirror conditions found in the natural environment

Answer 1

Answer: b. The researcher has a low degree of control over the conduct of the study.

Explanation:

In a laboratory experiment, the experimenter first proposes a hypothesis. He designs a laboratory which is suitable to test that hypothesis. If needed he will take natural environment as a reference to design the laboratory. Then each and everything in that laboratory will be under the control of the experimenter. Because he designed that laboratory and he knows each and every inch that laboratory. It means the researcher has a high degree of control over the conduct of the study. Thus, Statement B that the researcher has a low degree of control over the conduct of the study is not true.
