To calculate the standard deviation (represented by the symbol σ),
1. Calculate the mean (add up the measurements for each trial, then divide by the total number of trials)
2. Take the difference between each measurement and the mean.
3. Square the differences
4. Calculate the mean of the squared differences.
5. Take the square root.

the numbers are: 13.22, 13.48 cm, 13.49 cm, 13.49, 13.50

your math is still wrong.... (0.046656 + 0.001936 + 0.002916 + 0.002916 + 0.004096) = 0.05708 and divided by 5 is 0.011416

You're still doing it WRONG!
(0.046656 + 0.001936 + 0.002916 + 0.002916 + 0.004096) EQUALS 0.05708
YOU ONLY DIVIDE ONCE WHICH EQUALS 0.011416 !!
SO WHAT IS THE SQUARE ROOT OF 0.011416?!
