One advantage of using tests in research, rather than laboratory oberservation, is the usefulness of:

A) The presence of the researchers, which increases the reliability of the results

B) Describing behavior, rather than explaining it

C) Tests in clarifying the differences in the reactions of the same person on different occasions.

D) Having maximum control of the situation.

We ruled out (A) and (D) but i think its (B) and she believes its (C).

I think she is right. How do tests describe behavior better than laboratory observation does?

Thank you so much for your help! I'm sure as we review the rest we will need you :)

To determine which answer choice is correct, we need to weigh the advantages of using tests in research versus laboratory observation. Let's analyze option (B) and option (C) separately to see which one aligns better with the advantages of using tests.

(B) Describing behavior, rather than explaining it: One advantage of using tests is that they allow researchers to describe behavior accurately. Tests provide objective and measurable data that can be carefully recorded and analyzed. This is especially useful in research because it helps researchers avoid subjective bias and provides concrete evidence for their observations.

(C) Tests in clarifying the differences in the reactions of the same person on different occasions: Another advantage of using tests is their ability to measure and compare the reactions of individuals in different situations or on different occasions. By using tests, researchers can establish a baseline and determine changes or patterns in behavior over time or in different circumstances. This can be particularly valuable in understanding the causes and effects of various factors on behavior.

Comparing these two options, it appears that option (C) is more closely aligned with the advantages of using tests in research. While option (B) does highlight the importance of describing behavior accurately, option (C) specifically addresses the ability of tests to clarify differences in reactions over multiple instances.

Therefore, it is reasonable to conclude that the correct answer is (C) - tests are advantageous in clarifying the differences in the reactions of the same person on different occasions.
