Welcome to *cocron*!

This is a website allowing to conduct statistical comparisons between Cronbach alpha coefficients. Click "Start analysis" to begin!

The calculations rely on the tests implemented in the package *cocron* for the R programming language. A detailed documentation of all tests is available here.

You can integrate the R code generated by this web interface in your own R script. To do so, you can download the *cocron* package from here or r-project.org. Alternatively, you can type one of the following commands in the R console to install:

install.packages("cocron", lib="/my/own/R-packages/")

# alternative repository

install.packages("cocron", lib="/my/own/R-packages/", repo="http://comparingcronbachalphas.org/repo")

The *cocron* package also includes a GUI extension for the R front-end RKWard, which you can use instead of this web interface.
