Should you add heat? Tables 2 and 3 indicate how dry wheat and barley in natural-air drying bins will get during various weather conditions. Most years, weather in the upper Midwest is such that continuous fan operation (24 hours/day, 7 days/week) will dry either grain to 14% moisture or less.
Their IQ scores ranged from 77 to 135, with an average score of 112. Four years later, the same group took another IQ test. While the average score of 113 was only one point greater than the previous test, the range of scores was quite different: 87 to 143.our years later, the same group took another IQ test.

Researchers have developed IQ tests to try and create some kind of objective, quantitative measure of human intelligence. Despite their many flaws, IQ tests present a clear quantitative bell curve with 95% of their participants scoring within a range of 70 to 130. There are a couple different classifications of IQ scores. One common classification is Wechslerâs, which ranks 90-109 as the true average.
