The following table shows estimated average IQ among 8th graders taking the NAEP math and reading assessments in 2013 by the type of community where the school is located, broken out into four categories: City, suburb, town, and rural. The scores for both tests are on a 500 point scale, with a standard deviation of 37 on the math assessment and 34 on the reading assessment. In the subsequent table, these are converted into IQ estimates with a mean of 98–corresponding to the national average NAEP scores of 283.62 for math and 266.02 for reading–and a standard deviation of 15. The math and reading scores are weighted equally:
