Therefore, the standard deviation is 2. In this case 100% of the values in the population are at one standard deviation of the mean. The standard deviation is the most common measure of statistical dispersion, measuring how widely spread the values in a data set are. If the data points are close to the mean, then the standard deviation is small.

CHAPTER 1
(f) 4 The geometric mean of a series of returns is always larger than the arithmetic mean and the difference increases with the volatility of the series. (f) 5 The expected return is the average of all possible returns. (f) 6 Two measures of the risk premium are the standard deviation and the variance.

Standard Deviation Is Like An Average Of The Deviation: When we calculate the standard deviation, it is a way to get “an average deviation”. In this way, we then have a “typical” number we can use in discussions about the spread of the data. In our first step when calculating the standard deviation, we take our mean (typical value of ...
