The data set, you will rely on a formula that describes this in terms of n- . Just like the variance formula for the entire population, you will start this formula the same way. Follow the variance formula below: Variance = (Sum of each term – mean . Subtract the average from each value in your sample set. Just as you did with the entire data set, subtract your average from each term in your sample. Here is an example assuming the mean is and you have three values in your sample. Your differences will result in and ( ), respectively. . Square each of these differences . Once you have each difference, go ahead and square each of these values. Using the example values from the previous step, here are the resulting Whatsapp Number List products: and . With this example, you can see how the value (- ) is squared to give you a positive value. This is important and essential to the variance formula, because variance is more like an average of the point spread than a mean. Add up all the resulting squares . Just like the previous variance formula, add up all the products resulting from the second step: . Subtract one from the total number of values in your sample set. Before you divide, subtract one from the number of values in your sample set. Using the previous example, you only have three terms. Plug three into the n- part of the formula: n- . The result is two. . Divide the amount by the resulting n- difference. Finally, divide the sum from step three by two, as this is the difference you got in step four.
