Question

Answer 1

Answer: Reliable.

Step-by-step explanation:

Reliability is a term used in statistics and psychometric evaluations. These refer to the stability or consistency of the data obtained in an investigation.

For an investigation to be considered valid, it must be consistent over time, and under similar circumstances. Otherwise, it is considered that the research is not valid enough to accept the results obtained as accurate.
