Use Basic Formula Editor Features
The following example uses the Big Class.jmp sample data table to walk you through using the basic
features of the Formula Editor. You can find Big Class.jmp in the Sample Data folder, which was installed
when you installed JMP.
Big Class.jmp has a column called weight. Suppose you want a new column that computes standardized
weight values.
To create this column using a formula to obtain its values:
1. Open Big Class.jmp.
2. Select Cols > New Column.
3. Type the new name, Standard Weight, in the box beside Column Name.
4. Select Formula from the Column Properties menu.
5. Click the empty formula element in the formula editing area to select it.
When you create a formula and Show Boxing is checked, the selected portion of the formula is
outlined with a thin red line. See “Hide and Show Boxing” on page 221. All terms within the smallest
nesting box relative to the place that you clicked become selected, and the subsequent action applies to
those combined elements.
Next, enter the formula that standardizes the weight values.
1. While the initial missing term is selected, click weight in the formula element browser column selector
list.
2. Click the minus button in the Formula Editor keypad.
A new missing term appears after the minus sign as shown in Figure 7.10.
3. Click weight again.
4. Click the function browser menu, and select Statistical.
