Population standard deviation is used to set the width of Bollinger Bands, a widely adopted technical analysis tool. For example, the upper Bollinger Band is given as x + nÏ x. The most commonly used value for n is 2; there is about a five percent chance of going outside, assuming a normal distribution of returns.
