Using Data & Statistics The Data & Statistics application provides tools to: • visualize sets of data in different types of plots. • directly manipulate data sets to explore and visualize data relationships. Data changes in one application are dynamically applied to all linked applications. • explore central tendency and other statistical summary techniques. • fit functions to data. • create regression lines for scatter plots. • graph hypothesis tests and results (z- and t-tests) based on summary statistics definitions or data. Note: In the following example, Lists & Spreadsheet is shown along with Data & Statistics. This represents a typical page set-up.
