MEDIAN Meaning and
Definition
-
Median is a statistical measure that represents the middle value of a dataset when it is arranged in ascending or descending order. It is commonly used to describe the central tendency or the typical value in a set of numerical data. The median divides the dataset into two equal halves, with 50% of the values lying below it and the remaining 50% lying above it.
To calculate the median, the data points need to be sorted in an increasing or decreasing order. If the dataset has an odd number of values, the median is the middle value. For example, in a set of 7 numbers: 2, 4, 6, 8, 10, 12, 14, the median would be 8, as it is the fourth value when arranged in ascending order. If the dataset has an even number of values, the median is the average of the two middle values. For instance, in a set of 8 numbers: 3, 5, 7, 9, 11, 13, 15, 17, the median would be the average of 9 and 11, resulting in a median of 10.
The median is a robust measure compared to the mean as it is not influenced by extreme values or outliers in the dataset. It provides a more accurate representation of the central tendency when the dataset is skewed or contains extreme values. The median is widely used in various fields such as economics, finance, demography, and social sciences to summarize and analyze data distributions.
