Find the standard deviation of 4, 9, 11, 12, 17, 5, 8, 12, 14. First work out the mean: 10.222. Now, subtract the mean individually from each of the numbers given and square the result. This is equivalent to the (x - )Â² step. x refers to the values given in the question.
Population Standard Deviation Example: To find the Population Standard deviation of 1,2,3,4,5. Perform the steps 1 and 2 as seen in above example. Step 3: Now find the population standard deviation using the formula. â10/â5 = 1.414 . Variance Example: To find the Variance of 1,2,3,4,5. After finding the standard deviation square the values. (1.58113) 2 = 2.4999 Same for Population standard deviation
