Definition and calculation. 1.1 Standard deviation of a random variable. The standard deviation of a random variable X is defined as: where E(X) is the expected value of X. Not all random variables have a standard deviation, since these expected values need not exist. For example, the standard deviation of a random variable which follows a ...

Standard Deviation. The Standard Deviation is the square root of the variance. You can calculate it with the formula =sqrt(var(range)) or by using the appropriate function, either. stdev(range)or stdevp(range). Because of problems associated with Excel’s method of computing the standard deviation, we will usually calculate it by hand.

The ‘standard deviation’ is a measure of the spread of a set of values. Here it refers to the standard deviation of the population from which the different treatment groups were taken. In practice, however, this is almost never known, so it must be estimated either from the standard deviation of the control group, or from a ‘pooled ...
