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.

However all tests and scales use 100 as the IQ of a person of average intelligence. Since the average IQ is said to be 100, hence anything above 100 is considered as above average and below 100 as below average.IQ below 70 is taken as that of mentally challenged person.IQ above 140 is generally considered as that of a genius.We already know that IQ = Mental Age/Chronological Age X 100. Hence, the normal or average IQ score is 100, which means that the mental and chronological ages coincide. very small percentage of the population reaches an IQ of over 140. From this chart, it can be thus concluded that a normal IQ score is generally considered to be around the 100 mark. IQ scores are thus calculated on a scale of 0 to 200.
