...When considering more extreme possible returns or outcomes in future, an investor should expect results of as much as 10 percent plus or minus 60 pp, or a range from 70 percent to -50 percent, which includes outcomes for three standard deviations from the average return (about 99. 7 percent of probable returns).
...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 ± s, where µ is the arithmetic mean), about 95 percent are within two standard deviations (µ ± 2s), and about 99. 7 percent lie within three standard deviations (µ ± 3s).
... If the size (actual or relative to one another), mean, and standard deviation of two overlapping populations are known for the populations as well as their intersection, then the standard deviation of the overall population can still be calculated as follows:
There is absolutely nothing that isn't thoroughly covered in the book. It is straightforward, and does an excellent job of explaining all about Standard deviation in key topics and material. There is no reason to invest in any other materials to learn about Standard deviation. You'll understand it all.
