  1. On the WAIS-IV, what is the mean of the Full Scale IQ (FSIQ) standard score?

    Answer: 100

    Wechsler Full Scale IQ scores use a mean of 100 and a standard deviation of 15.

  2. What is the standard deviation of the Wechsler FSIQ scale?

    Answer: 15

    The FSIQ and index scores have a standard deviation of 15.

  3. Wechsler individual subtest scaled scores have a mean of what value?

    Answer: 10

    Subtest scaled scores are set to a mean of 10 with a standard deviation of 3.

  4. What is the standard deviation of a Wechsler subtest scaled score?

    Answer: 3

    Scaled scores range mostly 1–19 with a mean of 10 and SD of 3.

  5. An FSIQ of 130 is how many standard deviations above the mean?

    Answer: Two

    130 minus 100 equals 30, and 30 divided by the SD of 15 equals two SDs.

  6. Approximately what percentage of people score within one standard deviation (85–115) of the mean FSIQ?

    Answer: About 68%

    In a normal distribution roughly 68% of scores fall within one SD of the mean.

  7. A raw subtest score is converted to a scaled score primarily based on what?

    Answer: The examinee's age group norms

    Raw scores are converted to scaled scores using age-based normative tables.
