How To Calculate Pooled Standard Deviation - The pooled standard deviation is a method for estimating a single standard deviation to represent all independent samples or groups in your study when they are assumed to come from populations with a common standard deviation.
How To Calculate Pooled Standard Deviation - That is, if you have two data sets $x=(x_1,.,x_n)$ and $y = (y_1,., y_m)$, you want to determine the standard deviation of the aggregated data set, $z = (x_1,., x_n, y_1,., y_m)$, given knowledge of the means and standard deviations of $x$ and $y$. To calculate the pooled standard deviation for two groups, simply fill in the information below and then click the “calculate” button. The formula for calculating the pooled standard deviation is: Find the mserror, also called msresidual, and take its square root (ms stands for mean square, one of the columns in the anova table). The pooled standard deviation is a weighted average of two standard deviations from two different groups.
