In statpsych: Statistical Methods for Psychologists
size.ci.mean1 R Documentation
Sample size for a single mean confidence interval
Description
Computes the sample size required to estimate a single population mean with
desired confidence interval precision. Set the variance planning value to
the largest value within a plausible range for a conservatively large
sample size.
Usage
size.ci.mean1(alpha, var, w)
Arguments
alpha
alpha level for 1-alpha confidence
var
planning value of response variable variance
w
desired confidence interval width
Value
Returns the required sample size
Examples
size.ci.mean1(.05, 264.4, 10)
# Should return:
# Sample size
# [1,] 43
