Weighted Mean Formula The weighted mean is relatively easy to find. But insomecases the weights might not add up to 1. In those cases, you’ll need to use the weighted mean formula. The only difference between the formula and the steps above is that you divide by the sum of all the ...
How to Find the Mean from a Frequency Table The mean, or arithmetic average, is a common way to find the average of a set of data. To find the mean, we add up all of the data values and then divide by the number of values. The equation for this is: {eq}\frac{x_{1}+x_{2...
