Statgraphics Sigma express


STATGRAPHICS Sigma express is an "add-in" for Microsoft Excel that enables users to perform various calculations required when learning or applying Six Sigma. It adds a menu selection to Excel containing sections for each item of the DMAIC paradigm (Define, Measure, Analyze, Improve and Control) plus additional menu items for Tools and Help. The contents are sufficient to cover the needs of green belts and many black belts. In addition, it is similar enough to STATGRAPHICS Centurion that users can easily upgrade to that product if they need additional statistical capabilities.

Data Input

Data is selected by first highlighting it in your Excel worksheet. Specific columns are then selected through a standard STATGRAPHICS data input dialog box. Results are displayed by opening a STATGRAPHICS analysis window with multiple panes for tables and graphs. Users interact with the graphs in the same way as in STATGRAPHICS Centurion. When satisfied with the output, it may be pasted back into the Excel worksheet or into another application such as Word or PowerPoint.
