Central+Tendency

=Central Tendency=

In descriptive statistics, the measures of **central tendency** are the most commonly used metrics. The term **central tendency** refers to the "middle" value or perhaps a typical value of the data, and is measured using the **mean**, **median**, or **mode**.

The **mean** is calculated by dividing the sum of the scores in a distribution by the number of scores in the distribution. This value best reflects the typical score of a data set when there are few outliers and/or the dataset is generally symmetrical.

The **median** is the value which divides the values into two equal halves, with half of the values being lower than the median and half higher than the median.

The **mode** is the most frequently-occurring value (or values).
