NettetHow to Find the Mean. Finding the mean is very simple. Just add all the values and divide by the number of observations. The mean formula is below: For example, if the heights of five people are 48, 51, 52, 54, and 56 inches. Here’s how to find the mean: 48 + 51 + 52 + 54 + 56 / 5 = 52.2. Their average height is 52.2 inches.
