Consider the mode, median, and mean. Which average represents the middle value of a data distribution? Which average represents the most frequent value of a distribution? Which average takes all the specific values into account?

Calculating Mean, Median, and Mode (Individual Data) Individual data – represents individual values in a set. Mean – is the average value of the values in a set. It is calculated by dividing the sum of the individual values in a set by the number of values in that set. Median – better represents a measure of central than the mean in a set of data that are skewed one direction or another. To calculate the median value of individual...

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...
