This paper looks at some of the methods of estimating standard deviation (which I will usually refer to as โ€˜sigmaโ€™). Additionally, I propose a new formula for estimating sigma for small sample sizes and also present a means to mathematically evaluate these competing estimates of sigma. The question was posed to me: โ€œI have five […]
