I suspect I don't give enough six votes. Its a C, an average score, a solid middle of the road grade. If a normal curve applies, a lot more C grades are given than B or D grades. And the A grades and E or F grades, depending on how your school system works are relatively rarer than B or D grades. Now the ones, they are lower than the E or F. Six is a C, Five is a D, Four and below are failing grades.
Lets compare to IQ scores. 100 is average, a C. With a 15% standard deviation, 84 to 70 is a D. I think they used to call them morons. I found this on line: "What is the Difference Between a Moron, Imbecile and Idiot? It's true โ there's a difference. The three terms didn't start out as social insults either, in fact. In the early 1900s, psychologists used the terms to describe various levels of retardation. Those with an IQ of 0 to 25 (an IQ of 100 is average) were called idiots, 26 to 50 were called imbeciles and 51 to 70 were called morons. Morons could communicate and learn common tasks; imbeciles stalled mentally at about six years old; and idiots couldn't respond to stimulus or communicate with any level of competency".
70 is two standards deviations below the mean. "Many introductory statistics textbooks show how you can use the mean, standard deviation, and the normal distribution to make claims like approximately 2.5% of the sample is expected to score below two standard deviations below the mean." If an IQ of 55 is three standard deviations below the mean, then In statistics, the 68โ95โ99.7 rule is a shorthand used to remember the percentage of values that lie within a band around the mean in a normal distribution with a width of one, two and three standard deviations, respectively; more accurately, 68.27%, 95.45% and 99.73% of the values lie within one, two and three standard deviations of the mean, respectively. In mathematical notation. Of course remember to consider half these percentages are above and half are below the mean. 68.27% are within one standard deviation with 34.135% above or at the mean and 34.135% at or below the mean. I haven't seen an estimate for how many are exactly at the mean.
What all these math heavy statements are leading to is that one votes should be at least as rare as tens, considering six is average there are only four numbers higher but five lower than average. One is a lot less frequent than ten if the normal curve applies. Since there are lots more ones than expected by a normal curve, clearly votes on SOL aren't normal. If you vote one, a lot, you are not normal, either.
