Formula has been widely used in the U.S. for roughly six decades, feeding generations of infants who have flourished, said Dr. Steven Abrams, a University of Texas infant nutrition expert.

Doing this gives a monthly standard deviation (volatility) of 17.9% for Stock A and just 3.6% for Stock B. This confirms the optics in the chart.

The standard deviation formula for a sample is almost the same as the formula for a population, except you subtract N by 1 in the denominator, so it's: σ = √ (Σ (xi - μ)² / N-1).

For example, if your mean is in cell A2, population mean in cell B2, standard deviation in cell C2, square root of degrees of freedom in E2, type the formula as = (A2-B2)/ (C2/E2) to generate the ...
