This page is a form for calculating a confidence interval on a
coefficient of variation shared by k normally
distributed populations. Here is FORTRAN
source code for
a standalone program that calculates the confidence interval.
also have programs that do the following:
The theory behind these programs is described in three publications:
Confidence Bounds for Normal and Lognormal Distribution Coefficients of Variation,
2003, Research Paper 609, USDA Forest Products Laboratory, Madison, Wisconsin.
Confidence Bounds and Hypothesis Tests
for Normal Distribution Coefficients of Variation,
2007, Research Paper 638, USDA Forest Products Laboratory, Madison,

Hypothesis Tests for Normal Distribution Coefficients of Variation."
