How to calculate the pooled standard deviation, plus alternative formulas. σp: Standard deviation of p, SEp: Standard error of p The table below shows formulas for computing the standard deviation of statistics from simple random  The standard error is an important statistical measure and it is related to the standard deviation. The accuracy of a sample that represents a population is known  Standard Error of the Mean (a.k.a. the standard deviation of the sampling This last number doesn't even figure in the formula even though it did vary a bit in Of these, s is the estimate of the population standard deviation, t In the SD formula, the degrees of freedom are n minus 1 because the mean of the data has already been calculated (which imposes one condition or restriction  You should simply treat your SE as SD, and use exactly the same error propagation formulas. Indeed, standard error of the mean is nothing else than standard  the observations.

This function computes the standard deviation of the values in x. If na.rm is TRUE then missing values are removed before computation proceeds. Usage sd(x, na.rm = FALSE) Arguments. x.

• The SD quantifies scatter — how much the values vary from one another. • The SEM quantifies how precisely you know the true mean of the population. It takes into account both the value of the SD and the sample size. • Both SD and SEM are in the same units -- the units of the data. • The SEM, by definition, is always smaller than the SD.
