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.

On the majority of modern IQ tests, the average IQ Score is set at 100 with a standard deviation of 15 so that IQ scores follow a normal distribution of statistical data. This means that approximately 95% of the worldâs population have scores within two standard deviations (SD) of the mean (average IQ score). If one SD is 15 points, as is common in almost all modern tests, then 95% of the population are within a range of 70 to 130, and 98% are below 131.
