Central tendency meaning

Central tendency definitions

Central tendency is a statistical measure that represents the single value around which the entire data set tends to cluster. It provides a central point or a typical value for a data set. There are three main measures of central tendency: mean, median, and mode.

Mean

The mean is the average of a set of values calculated by adding all the values and dividing by the total number of values. It is the most common measure of central tendency used in statistics. The mean is sensitive to extreme values, also known as outliers, which can significantly affect its value.

Median

The median is the middle value in a data set when the values are arranged in ascending or descending order. If there is an even number of values, the median is the average of the two middle values. The median is often used when there are outliers present in the data, as it is not influenced by extreme values.

Mode

The mode is the value that appears most frequently in a data set. A data set can have one mode (unimodal), two modes (bimodal), or more than two modes (multimodal). The mode is useful for categorical data and nominal data, where there is no inherent ordering of values. Unlike the mean and median, the mode can be used for any type of data.

Each measure of central tendency has its advantages and limitations, and the choice of which to use depends on the nature of the data and the research question being asked. By understanding central tendency, researchers and analysts can gain insights into the characteristics of a data set and make informed decisions based on the central values that best represent the data.
