3. Copy from a text file with data or a spreadsheet.

• Calculate various statistics, critical values and p-values.

1. The MAPPING button must be clicked to map the variables, e.g. assigning variables to either the regressor or the response, in a simple linear regression.
2. After all the above it set, the CALCULATE button generates statistical results.

• Summarize the results.

1. The RESULT button leads to statistical results such as summary statistics and parameter estimates. The form and

contents of the result depends on type of analyses.

1. The GRAPH button displays data scatter plots, regression diagnostics, etc.

• If you don't like something you did, or want to clear a previous example, use the CLEAR button. Note that this also clears out the data you entered earlier.
