Description
SD_pool is a function for estimating a population standard deviation.
The equation comes from Morris (2008) who recommends pooling the pre-test
standard deviations of the control group and treatment group.
Usage
1
sd_pool(sd_t, sd_c, n_t, n_c)
Arguments
sd_t
Pre-treatment standard deviation of the treatment group.
sd_c
Pre-treatment standard deviation of the control group.
n_t
Number of subjects in the treatment group.
n_c
Number of subjects in the control group.
Value
Pooled standard deviation.
