Last but not least, the software contains a various amount of different statistical graph designs, interpretations and analysis functions.
Statistical Software and Advisor
SigmaStat is an easy-to-use, wizard -based statistical software package designed to guide users through every step of the analysis and perform powerful statistical analysis without being a statistical expert.
SigmaStat is tailored to the areas of life science and medical research, but can be a valuable product to scientists in many fields. With SigmaStat, you can be confident that you have analyzed your data correctly.
Because it takes you step by step through the analysis, SigmaStat ensures that you:use the proper statistical method to analyze your data,
avoid the risk of statistical error,
interpret the results correctly,
generate an appropriate display and a professional report
Features that make Analysis fast and easy
You don't need to know which statistical test is right for your data. Simply open the SigmaStat Advisor Wizard and answer a few questions about your data and your research project. The Advisor will suggest the appropriate statistical test. Then SigmaStat runs the test, checking your data against the test's underlying assumptions. If your data violates any of those assumptions, another test may be suggested that you can run immediately. After you run the test, you receive a report in plain English, interpreting the results. Then, with a click of a mouse, you can visualize your data in one of several pre-selected formats
SigmaStat provides additional functions for analysis, interpretation and graphical visualisation of your data.
When you conduct an analysis with SigmaStat, you receive a detailed, formatted report interpreting the results - not in statistical jargon, but in language you understand. You can print your report, incorporate it into other documents or export it in a variety of formats, including PDF and HTML
SigmaStats Result Graphs
You can instantly visualize the results of your analysis by clicking on one of the preselected graph types suggested by SigmaStat.
SigmaStats Graph Wizard
Simple choose the graph type - point plot, box plot, bar chart, histogram, scatterplot, step plot and more. SigmaStats Graph Wizard will guide you through the process of selecting your data and creating the graph.
SigmaStats Graph Properties-Dialog
Edit every detail of your graph in SigmaStats new Graph Properties-Dialog.
