SpletTo 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 ...
