What is the term used to describe the middle value in a series of values arranged in order of magnitude?

The middle value in a series of values arranged in order of magnitude is referred to as the median. To determine the median, one would first sort the numbers in ascending order and then select the middle number. If there is an even number of values, the median is calculated by taking the average of the two middle numbers. This measure is particularly useful in statistics because it accurately represents the center of a data set, especially when the data contains outliers or is skewed.

In contrast, the mean is the average of all values in a dataset, calculated by summing all the values and dividing by the count of values. Mean average is essentially a redundancy since "mean" already implies an average. The mode represents the value that appears most frequently in a dataset. Each of these terms has its particular application in data analysis, but when specifically looking for the middle value, the median is the appropriate term to use.
