JMP Tutorial
1. Start JMP IN by double-clicking its icon on the desktop.
2. The JMP Starter panel: this contains most of the items on the various menus on
the standard menu bar, but organized more thematically: File, Basic Stats,
Modeling, etc. Take some time to click the various tabs to see what’s there. (If
you close the JMP Starter, you can always re-open it from the menu bar: Window
-> JMP Starter.)
3. Opening JMP files: From the JMP Starter panel File tab, click Open Data Table.
Navigate to the N: drive (“Sasuser on Lancelot…”), then to psy3030/jmp/
and open therapy.jmp.
4. The Rows and Cols menus: On the menu bar, the Rows and Cols menus provide
various controls for the rows (observations) and columns (variables) of the data
table. Similar menus appear when you click the small red triangles in the left
panel next to the data table, or in the upper left of the data table itself.
5. Use a variable as a label: From the data table, select the NAME variable, then
from the Cols menu, select Label/Unlabel. Note the small label icon which
appears next to the NAME variable in the left panel.
6. Set color and marker from a variable. From the data table, select the SEX
variable. Then, from the Rows menu, select Color or mark by column… Check
Set color by value and Set marker by value, then click OK.
7. Exploratory plots: From the Multivariate tab of the JMP Starter, click
Multivariate button. In the Multivariate and Correlations panel, note that the list
of variables from the therapy table appears, with C (for character) or N (for
numeric). The Y, Columns region tells you that you must select two or more
numeric variables--- select all the numeric variables (click the first, then shift-
click on the last), then click the Y, columns button, then OK.
8. Tools menu and Tool bars: The items on the tools menu and the tool bar allow
special mouse actions to interact with plots and with the data table. The default
tool is the Arrow, which selects rows or columns in the data table, and individual
points in a plot. For example, use the Arrow tool to select Tina in the data table,
and in one of the scatterplots. Also, try the Brush tool to select a rectangular
region in one of the plots—say all the males in the plot of Improvement vs. Sex.
(Click a point to start a selection, then Alt-Click to extent it.)
9. Fit a model: From the Modeling tab in the JMP Starter, click the Fit Model
button. Give Improvement the Y role, and add the Personality test to the Model
effects panel. Click Run Model to, well, run this model.
