Take a practice IQ test (although not a valid or reliable measure of
your intelligence) and read the sample report generated. Notice the
adjusted score and where your score falls on the bell curve, the range
and percentile score as well as the descriptor. Be sure to convert your
scores to the Catell and Stanford Binet scales and notice if there are
any differences. Use the link to the IQ Testing Lab provided:
Please note that
Prepare a brief overview (1 page in length; you may put
this in a table or paragraph form) of your results, the conversions,
and any differences that occur. Then respond in a 3-5 page, APA
formatted paper to the following:
- In your opinion, was this a fair measurement of
your intelligence? Why or why not? Support your answer with what you
have learned about IQ tests.
- Discuss possible limitations with interpretation of
your results within the context of what you have learned about
psychometric test properties. How would you explain the reliability and
validity of this test to someone who has not taken this course?
- Explain whether you felt this test minimized cultural bias, based on what you have learned so far.
- What ethical limitations might prevent the use of
this type of test in major decision-making (e.g., entrance to college,
identifying disabilities, etc.)?
- Analyze the possible influence of the format of the
test (e.g., computer versus manipulatives or paper, timed versus
untimed, standardization, multiple choice, etc.) on your results, based
on what you have learned about various testing instruments so far.
