52.1 Three primary statistics are used to describe a variable's central tendency, defined as the average behavior of the variable. You can use these statistics, known as the mean, the median, and the mode, to draw meaningful conclusions about a variable's past behavior and to predict its future behaviar An investor is considering a stock with the following returns over the past 12 years: Year Annual Return Year Annual Return 12 10 12 The mean, also known as the arithmetic...
