A statistical software package for manufacturing and business applications is disclosed. The software package comprises an improved user interface that supports data collection, entry, and analysis features for manufacturing and business applications. Data entry is simplified by prompting the user for no more data than is needed to perform calculations and analysis. The software completes complex data analysis, interprets the data in the background, and reports simple analysis results to the user about the data that has been entered. The software supports user conducted tests but decides which test or tests are appropriate test and which results are relevant for the user. In an example embodiment, the software package is implemented as a web-based application with a central database accessible through a web service to provide support to the user. In an example embodiment, the application provides data collection, data entry, analysis, interpretation, graphing, and reporting functionality.
