not valid but still reliable

Explanation:

Based on the information provided in regards to the situation at hand, it can be said that the test is very reliable, but not valid in this situation. The test is reliable because it provides the same results regardless of how many times it is taken. Unfortunately, it is not valid because it does not measure intelligence as it was designed for, but instead it measures personality.

Rosy · Answer 2

The researcher's new test is reliable, but not valid.

Explanation:

It is a common mistake to assume the terms "validity" and "reliability" have the same meaning.

If an assessment is reliable, your results will be very similar no matter when you take the test. If the results are inconsistent, the test is not considered reliable.

An assessment validity refers to how well a test measures what it is supposed to measure

An assessment can provide you with consistent results, making it reliable, but unless it is measuring what you are supposed to measure, it is not valid.
