Using a taxonomy of errors as a conceptual framework for differences in patterns of use for casual and novice users

A taxonomy of errors was applied in a recent study of casual and novice users of a statistical analysis software. The taxonomy was found to be useful and several extensions to the taxonomy were proposed. The aim of this study is to confirm the theoretical validity of the proposed extensions and the usefulness of the taxonomy in describing the patterns of human-computer interaction and predicting changes in use patterns with learning.
