Meaning and Objectives of Measuring Central Tendency

The term measure of central tendency can be described as a single value which is used to define a set of data by classifying the central position within that set of data. That’s the reason measures of central tendency is also known as measures of central location. It is also categorised as summary statistics. Here, the mean (usually known as the average) mostly measure the central tendency which is the most common, apart from the median and the mode.

All three mean, median, and mode are the types of central tendency, however, they have different measures and conditions.
