Standard deviation is the method to measure the market volatility by traders as well as analysts. This measuring metrics shows the price movement of the stocks from its base price in a specific time frame. This is done by calculating the base price for that time and then subtracting from each of the price point. The volatility is calculated as the square root of the variance, S. This can be calculated as V=sqrt(S). This "square root" measures the deviation of a set of returns (perhaps daily, weekly or monthly returns) from their mean. It is also called the Root Mean Square, or RMS, of the deviations from the mean return. While standard deviation determines the volatility of a fund according to the disparity of its returns over a period of time, beta, another useful statistical measure, compares the volatility (or How to Calculate Volatility. Find the mean of the data set. This means adding each value, and then dividing it by the number of values. If we add, $1, plus $2, plus $3, all Calculate the difference between each data value and the mean . This is often called deviation.
