  1. How to Calculate Standard Deviation?

  2. To Find the Standard Deviation, follow the below steps Step 1: Find the mean. Step 2: Take each number, subtract the mean and square the result. Step 3: Calculate the sum of squared differences Step 4: Calculate the standard Deviation Formula:

  3. Step 1: Find the mean Given Numbers: 10, 20, 30, 40, 50 10+20+30+40+50 = _______________ 5 150 = _____ = 30 5

  4. Step 2: Take each number, subtract the mean and square the result = (10-30)^2 = (-20)^2 = 400 = (20-30)^2 = (-10)^2 = 100 = (30-30)^2 = (0)^2 = 0 = (40-30)^2 = (10)^2 = 100 = (50-30)^2 = (20)^2 = 400

  5. Step 3: Calculate the sum of squared differences = 400 + 100 + 0 + 100 + 400 = 1000

  6. Step 4: Calculate the Standard Deviation = √(1000) / (5-1)) = √ ((1000) / (4)) = √250 S = 15.811
