The comment uses a definition of average as scores within one standard deviation of the mean. (The comment also uses average as the mean score, 100, which makes it confusing--two meanings of average. NB: Mean is also median in normal distributions.)
- wizofaus 4y agoI suppose it's the redefinition of average to include IQs up to "115" that I'd say was the issue then...
- wahern 4y agoTIL that apparently both Stanford-Binet and Wechsler have classification systems which both define "average" as 90-109. See https://en.wikipedia.org/wiki/IQ_classification https://en.wikipedia.org/wiki/IQ_classification and https://en.wikipedia.org/wiki/Stanford%E2%80%93Binet_Intelligence_Scales https://en.wikipedia.org/wiki/Stanford%E2%80%93Binet_Intelli... (the latter includes the latest scale for Standford-Binet) Google provides many hits of people using average to mean within one standard deviation, or 85-115, but in a few minutes of searching I couldn't figure out a proper authority for that.
