The terms mean and average are often used interchangeably, but they have subtle differences in their usage. The meanspecifically refers to the arithmetic mean, which is calculated by summing all the numbers in a data set and dividing by the count of numbers. It is one type of average.
On the other hand, average is a broader term that can refer to various measures of central tendency, including mean, median, and mode. While in most cases “average” refers to the mean, the context may vary. For example, in statistics, different types of averages might be used depending on the data distribution.
