Symmetries of Equations: An Introduction to Galois Theory

Thus Galois theory was originally motivated by the desire to understand, in a much more precise way than they hitherto had been, the solutions to polynomial equations. Galois’ idea was this: study the solutions by studying their “symmetries” .

Mean and Standard Deviation - University of York

standard deviation, usually denoted by s. It is often abbreviated to SD. For the FEV data, the standard deviation = 0.449 = 0.67 litres. Figure 2 shows the relationship between mean, standard deviation and frequency distribution for FEV1. Because standard deviation is a measure of variability about the mean, this is shown
