An algorithmic error has been detected in EduG Version 5.  Components of variance for interactions involving fixed facets are not always correctly computed. The problem has been resolved in Version 6, which is available for download under the name EduG 6.1 e by clicking on the following link : EduG 6.1 e

If you have previously downloaded an earlier version of EduG, you are advised to replace it immediately with Version 6.1 - e, and to use it to check the results of any G studies you analysed using the earlier version, where these involved fixed facets.

When working interactively with the book Applying Generalizability Theory using EduG, it is nevertheless preferable to continue using Version 5 of EduG, re-distributed here under the name  of PREVIOUS EduG, since the worked examples were prepared using this version.
