Since education is highly correlate

Since education is highly correlated with IQ scale obtained from the stanford-binet and the wechsler adult intelligence scale , one would expect the average IQ for the Annadale samble to be lower than that of the of the general population.
Considering the restriction in education of the Annadale subject, it would also be reasonable to expect some restriction in the variability of IQs. The wechsler adult intellignce scale data conform to such expectations but the S-B data do not.
