Answer 1

Answer:

poor; good

Explanation:

Validity: In research, the term "validity" is determined as the extent or degree to which a specific test or research claims to compute or measure. However, it is considered as important for a test or a research to be valid in order to for the results to be properly interpreted and accurately applied.

Reliability: In research, the term "reliability" is determined as the consistency of a particular test or research. In other words, a particular test should give rise to the similar results if measured at an interval of time.

In the question above, the given method has poor validity and good reliability.
