Name the three measures of central tendency. Describe the measures of central tendency. Under what condition(s) should each one be used? What are the properties of a good measure of central tendency? What is the purpose for obtaining a measure of central tendency?
Another commonly used measure of central tendency in specific cases is the mode. Themodeis simply the most commonly occurring value. For example, in a class of 50 students graded on a scale of 1-5, the distribution may be as shown in the figure. The mode of this data is 4. ...
There are many indices of the middle, or central tendency, of a set of numbers, including the mode, median, and mean. Indeed, there are, several "means," of which the arithmetic mean is only one. When data are skewed, or when there are outliers at one or both ends of the ...

One of the most commonly used absolute risk metrics is standard deviation, which is a statistical measure ofdispersionaround a central tendency.
