JMP Correlation

Purpose: Suppose we wish to examine the burglary-larceny relationship using correlation. The data is stored in the data file "crime.jmp".

1) To open JMP, select Start/Programs/JMP IN 4/JMP IN 4. The initial
viewing screen is the JMPIN Starter menu. To analyze an existing data file,
select Open Data Table.

2) This opens the Open Data File menu. Double-click on the folder JMP IN Data.

3) Use the slide bar to scroll to the file "Crime.JMP" found within the JMP IN Data folder.
Double-click the file.

4) Now that we've accessed the desired data file, we can run analyses.

5) To compute correlations, select Analyze/Multivariate from the menu options at
the top of the screen. Under "Select Columns", hold down the Ctrl key and single-click the variables of interest (i.e., burglary and larceny). Next, single-click the Y, Columns button and select OK.

6) The burglary-larceny correlation, 0.7921, is output.

7) Explore options by simply clicking on buttons. Red arrows beside headings open menus;
blue arrows collapse or open windows.

8) Simple trial and error experimentation often works well. When this is ineffective, select Help from the menu found at the top of the screen.
