Hi,

You can use the function module

1. 'QRKT_STD_DEVIATION_SHEWHART'-Algorithms for Shewhart chart for s with internal dispersion and mean line

2.'QRKT_STD_DEVIATION_SHEWHART_2'- Algorithms for Shewhart chart for s with overall dispersion and mean line.

You could also calculate it yourself of course - standard deviation is the square root of the sum of the square of the differences between the mean and each value divided by the number of values you have less one.

Hope this helps.
