If 5 is moved from S to R, then the arithmetic mean of R increases to 3, and the arithmetic mean of S increases to 7.5, even though the total set of numbers themselves, and therefore their overall average, have not changed. Consider this more dramatic example, where the arithmetic means of sets R and S, are 1.5 and 10 033, respectively:
Christopher Michael Langan (born March 25, 1952) is an American horse rancher and former bar bouncer, known for scoring highly on an IQ test that gained him entry to a high IQ society, and for being formerly listed in the Guinness Book of Records high IQ section under the pseudonym of Eric Hart, alongside Marilyn vos Savant and Keith Raniere ...
IQ scores can differ to some degree for the same person on different IQ tests, so a person does not always belong to the same IQ score range each time the person is tested (IQ score table data and pupil pseudonyms adapted from description of KABC-II norming study cited in Kaufman 2009).

Youngest or middle siblings may beg to differ, but this study of 250,000 Norwegian 18- and 19-year-olds published in Science magazine revealed they had an average IQ 2.3 points higher than their ...
The average farm size was 328 acres (133 ha), significantly less than the average farm size in the U.S. of 444 acres (180 ha). [ 1 ] Because of its scale, and the naturally arid climate, the agricultural sector uses about 40 percent of California's water consumption . [ 2 ]
California’s farmers would also likely suffer as well — and, with it, America and the world’s food supply. Opinion Today’s farmer relies more on technology than ever before.
With regard to the potential causes of these gaps, the authors stated that there was insufficient evidence at the time to make conclusions. [1] Today, the scientific consensus is that genetics does not explain observed differences in average IQ test performance between groups, and that these differences are environmental in origin.
