Answer:Dr. Phillips is confident in this test's validity
Step-by-step explanation:
Validity refers to the fact that the test measures what it claims to measure , this means when a test is done it will give the result that measures exactly what was being tested otherwise the test will have low validity of it doesn't measure what it claims to measure.
Dr Philips says this test is an accurate measure of personality which means this is a test used to test personality and it actual measures personality as it claims.
If the result read differently from what personality result will look like then that would have low validity but it means Dr Philips has used this test and the result he has received were consistent with the result you will expect to get when testing a personality and he then trust it's validity.
