To calculate the variance follow these steps: Work out the Mean (the simple average of the numbers) Then for each number: subtract the Mean and square the result (the squared difference). Then work out the average of those squared differences. (Why Square?)
21 Aug 2009 In order to understand what you are calculating with the variance, break it down into steps: Step 1: Calculate the mean (the average weight). Step 2: Subtract the mean and square the result. Step 3: Work out the average of those differences.
