Sample Mean: What It Is and How to Calculate It
In statistics, the sample mean is a commonly used measure of central tendency that represents the average value of a sample of data. It is calculated by adding up all of the values in the sample and dividing by the number of values.
For example, let's say we have a sample of test scores for 10 students:
78, 85, 92, 76, 89, 80, 87, 84, 91, 83
