Standard Deviation from the Pooled Standard Error
Description
IMPORTANT: For a single group, use SD_from_SE()
!
Calculates the standard deviation from the pooled standard error and sample sizes of two groups (e.g., for intervention effects). This method is the reverse of SEp_from_SDp()
.
Usage
SDp_from_SEp(SEp, n1, n2)
Arguments
SEp |
pooled standard error |
n1 |
sample size group 1 |
n2 |
sample size group 2 |
Value
Pooled standard deviation

if the standard error should be computed instead.
Examples
#pooled standard error, sample size 1 and sample size 2
SE <- 0.12
n1 <- 140
n2 <- 140
