Which IQ score is used as the threshold indicating potential mental retardation in the source material?

Explanation:
An IQ score of 70 is used as the threshold indicating potential intellectual disability because it sits about two standard deviations below the average (mean ~100, SD ~15). Scoring 70 or below flags possible cognitive deficits and prompts a fuller assessment of adaptive functioning and developmental history. The other numbers reflect average or milder deviations (100 is typical, 85 is about one SD below, and 75 is a borderline range) and do not meet the established cutoff. Remember, diagnosis also relies on deficits in adaptive functioning and onset during the developmental period, not IQ alone.
