In class today we corrected lesson 2 standard deviation numbers 1 - 6. When finding the square root the number will always be positive. To find the range you must subtract the biggest number and the smallest number. To find the mean you must add all the numbers and then divede them by how many numbers there are Ex: 57+58+59+60/4 = 58.5 = th mean.
