Chebyshev's rule standard deviation

WebAug 21, 2024 · Chebyshev's inequality, also known as Chebyshev's theorem, makes a fairly broad but useful statement about data dispersion for almost any data distribution. This theorem states that no more than 1 / k2 of the distribution's values will be more than k standard deviations away from the mean. The rule is often called Chebyshev's … WebTo calculate "within 1 standard deviation," you need to subtract 1 standard deviation from the mean, then add 1 standard deviation to the mean. That will give you the range for 68% of the data values. 285− 37 = 248 285 − 37 = 248 285+ 37 = 322 285 + 37 = 322 The range of numbers is 248 to 322. The second part of the empirical rule states ...
