I am happy to see that more and more people are using the Real Statistics Using Excel website since its release in March. As described on the Home page, this website provides the resources necessary to perform statistical analysis in the Excel environment.
In the past few weeks I have made a few bug fixes (e.g. fixing the QQ Plot data analysis tool), and so if you have an earlier version of the Real Statistics Resource Pack, you might want to download the latest version. You can learn which release you have by entering the function VER() in any worksheet. The latest version is 1.3.
I expect to put another release out in a couple of weeks which provides improved versions of some of the existing functions and tools. I am testing it now.
I also expect to issue a multivariate statistics release (release 2.0) by end of the summer. This will provide functionality such as MANOVA and Factor Analysis. Stay tuned.
