A central concern when using Excel is whether the data being used is sufficiently clean and well-organized to be useful for further analysis. In the Excel Data Management course, we cover the importing of data from other sources, cleaning it, validating data at the point of data entry, protecting it from unauthorized changes, and organizing it properly. The outcome is much more reliable data, which improves the quality of any subsequent analyses conducted on the data. Course level: Basic. Prerequisites: None. Course includes integrated text and study guide, final exam, and grading service.
