The Median: A Key Measure Of Central Tendency In Math And Statistics

Median

connects vertex to midpoint of opposite side

The median is a statistical measure of central tendency that represents the middle value of a set of ordered numbers. It is the value that separates the upper 50% from the lower 50% of the data. To calculate the median of a set of numbers, you need to arrange them in ascending or descending order and select the middle value.

If the dataset has an odd number of values, the median is the middle value. For example, if you have the following dataset: 2, 5, 7, 9, 11, the median is 7 as it is the middle value.

If the dataset has an even number of values, the median is the mean of the two middle values. For example, if you have the following dataset: 3, 6, 8, 12, the median is (6 + 8)/2 = 7.

The median is a useful measure of central tendency as it is less affected by extreme values or outliers compared to the mean. It is often used in descriptive statistics to describe the center of a dataset.
