The mean (aka the arithmetic mean, different from the geometric mean) of a dataset is the sum of all values divided by the total number of values. It’s the most commonly used measure of central tendency and is often referred to as the “average.”
How to Find the Mean. Add up all data values to get the sum; Count the number of values in your data set; Divide the sum by the count; The mean is the same as the average value in a data set. Mean Formula. The mean x̄ of a data set is the sum of all the data divided by the count n.
The mean (aka average) summarizes a dataset with a single number representing the center point or typical value. Learn how to find the mean.
