Central tendency is a key property that describes a data set. Central tendency refers to the single typical value which describes a data set. Arithmetic mean or Mean, Median and Mode are examples of the measures of central tendency.
- Mean, the most frequently used measure of central tendency is the sum of variables divided by the total number of variables. This measure of central tendency is used when the data set does not involve extreme values.
- Median, a tool of central tendency,is the middle value when a set of numbers are arranged in ascending order. This measure of central tendency is used when the data set has extreme values.
- Mode is the most frequently used value in the data set. This measure of central tendency is not influenced by extreme values in the data set
As against central tendency, which describes the central location of a data set, measures of non central location are quartiles.
