1. compute the average: add the values and divide by 5 
Average =(36+ 40+24+24+31)/5=31.0
--
2. Compute the deviations from the average
dev:  (36-31)=5, (40-31)=9,etc
--
3. Square the deviations and add
sum (dev^2):  5^2+9^+...+0^2=204
--
4. Divide step #3 by the sample size=5 (typically you divide by sample size-1 to get the sample standard deviation, but you are assuming the 5 values are the population, so no need to subtract 1, from the sample size.  This result is the variance
Variance =204/5=40.8
--
5. Standard deviation = sqrt(variance)
standard deviation= sqrt(40.8)  </PRE>
