The 1st stand dev...........is 68 %,,,,,,,,,,,,,,,,,,,,6 + 8 = 14.............like 14i.........adding the single digits to the double digits........embodied in the ratio........1/2.............single.......like one.......double like 2...........and reflex. sym..........with the sine of 60 degrees.......................................the 2nd stand dev...........is 95 %...........added single digits to its double digit.............9 + 5 = 14.................
If a data distribution is approximately normal then about 68 percent of the data values are within one standard deviation of the mean (mathematically, μ ± σ, where μ is the arithmetic mean), about 95 percent are within two standard deviations (μ ± 2σ), and about 99.7 percent lie within three standard deviations (μ ± 3σ ...
