Research has shown that the Wechsler test is one of the most well-designed tests to measure intelligence. However, as most tests of this nature are, the tests are only as reliable as the person giving them.
Similarly, is the WAIS IV reliable and valid?
Reliability and Validity The Wechsler Adult Intelligence is a well-established scale and it has fairly high consistency. Over a two to twelve week time period, the test-retest reliabilities ranged from 0.70 (7 subscales) to 0.90 (2 subscales).
Likewise, why are the Wechsler tests important? The goal of his original test was to help identify children who needed specialized help in school and he felt that a variety of individual factors, including a child’s level of motivation, could influence test scores.
In this manner, what does the Wechsler test measure?
