A researcher administers a standardized test to the students in a school testing a new program as well as to students in a similar school as a control group. To what extent is comparison of the average scores for the two groups of students useful for determining the effects of the program?
Of limited usefulness as a pilot study but has many threats to validity T/F

True.

Explanation:

An investigator administers a practice test as the intervention group for all the participants in a school testing out a new curriculum as well as for the participants in the individual school. The analysis of just the scores for the two groups of students is thus of limited usefulness as a pilot study but has many challenges to the point that it is useful to assess the results of the program.
