Explanation / Answer

Mean = Sum of observations/ Count of observations
Mean = (7 + 5 + 6 + 5 + 8 / 5) = 6.2
Variance
Step 1: Add them up
7 + 5 + 6 + 5 + 8 = 31
Step 2: Square your answer
31*31 =961
…and divide by the number of items. We have 5 items , 961/5 = 192.2
Set this number aside for a moment.
Step 3: Take your set of original numbers from Step 1, and square them individually this time
7^2 + 5^2 + 6^2 + 5^2 + 8^2 = 199
Step 4: Subtract the amount in Step 2 from the amount in Step 3
199 - 192.2 = 6.8
Step 5: Subtract 1 from the number of items in your data set, 5 - 1 = 4
Step 6: Divide the number in Step 4 by the number in Step 5. This gives you the variance
6.8 / 4 = 1.7
Step 7: Take the square root of your answer from Step 6. This gives you the standard deviation
1.3038
