Question

After learning about his low score on the Wechsler Adult Intelligence Scale, Gunter complained, "I don't believe that test is a measure of intelligence at all." Gunter's statement is equivalent to saying that the WAIS lacks_________.
a) standardization
b) reliability
c) validity
d) a normal distribution

Answer 1

Answer:

c) validity

Explanation:

Validity: In psychology, the term validity refers to the tendency of a test to measure what the test is supposed or claims to measure. It is the judgement which is based on different types of evidence.

In other words, it is the extent to which a particular conclusion, concept, or measurement is well-defined and responds accurately or precisely in the real world.

The validity of an experiment can be increased by improving measurement techniques, controlling different variables, adding placebo or control groups, etc.

In the question above, Gunter's statement is equivalent to saying that the WAIS lacks the validity.
