The standard deviation of an entire population is known as sigma and is calculated using: Where x represents each value in the population, μ is the mean value of the population, Σ is the summation (or total), and N is the number of values in the population. So, to do this calculation, you need to find the mean of the numbers. To do this, you need to total all the numbers and divide by the number of values. Then you need to total the difference between each number and the mean. Then you need to square this result, divide this square by the N and find the square root of this value. You will need to store the number in a list in order to access them for calculating the mean and then again to calculate the sum of the differences between the numbers and the mean.
