Evaluate the Weschler Scale of Intelligence. You are free to use any of the scales, but it may be best to use the WAIS as we have covered this scale more in depth in class. Your evaluation should include the following:
(1) dimensionality (define this term, and explain if this is achieved in this assessment)
(2) reliability (define this term, and explain if this is achieved in this assessment)
(3) validity (define this term and explain if this is achieved in this assessment)
(4) perform an item analysis (define this term and use 1 or two test items and explain whether they are reliable and valid )
(5) describe biases of this test overall, and through item analysis (define what biases you feel do/do not exist)
(6) discussion- the report detailing your measure should conclude with a discussion that outlines the strengths and weaknesses of the measure overall, and what changes you would make in a hypothetical revision of the measure.
APA writing format is required. You should have a title page, introduction page, and references. This paper should be 7-10 pages, not including the title and reference pages.
-I’ve already written two pages for this paper which are located in the files and I would like you to proofread it along with writing 5 more pages relating to it (equaling 7 pages). Follow the instruction given above.
You will not be graded based upon the quality or psychometric strengths of your test or scale, but rather based upon how well you demonstrate that you understand and can employ rigorous psychometric methods to assess its strengths and weaknesses.
