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.
