Answer :
c. Juan's IQ is in the low average range, Juan's score of 85 on the WISC-IV places him in the low average range of IQ scores. This means his IQ is one standard deviation below the mean but still within the average range.
When analyzing IQ scores, it is important to understand the range of the scores and their implications. The Wechsler Intelligence Scale for Children (WISC-IV) scores are typically classified based on a bell curve distribution, where the average IQ score is 100 with a standard deviation of 15. This means that a score of 85 falls one standard deviation below the mean.
Given that Juan scored an 85 on the WISC-IV, Juan's IQ is in the low average range. A score between 85 and 115 is generally considered average intelligence. Specifically, a score of 85 indicates that Juan falls just one standard deviation below the average, denoting that while his IQ is on the lower side of average, it does not suggest intellectual disability or significant cognitive delays.
