Standard Deviation, How is it calculated?

[MercySakesAlive]

Is there a formula for the global standard deviation that I can use that considers the frequency of each true count, the standard deviation at each true count, and how much you bet at each true count? Thank you.

See BJA3, bottom of p. 19, all of p. 20.
