Rural-Urban Differences in Intelligence

Rural-Urban Differences in Intelligence
https://www.jstor.org/stable/27530288
про то, почему деревенские дети
глупее городских

...Numerous investigators have shown that urban
children have a higher mean IQ than their rural
counterparts. When the writer surveyed the literature on
rural-urban differences in intelligence, he found that
many of them did not determine whether the difference in
favor of the urban children was significant. The writer
chose nine such studies for a composite analysis and found
the difference infa vor of the urban children to be
significant beyond the five per cent level. Table III
reveals that when the various studies were treated as
clusters from a common population and tested for
difference by using cluster sampling techniques, the
difference in favor of the urban children is significant
beyond the 0.1 per cent level.
