& StatMode

In a program, store the constant name (or its number) into the variable StatMode. 1VAR =1, 2VAR=2.

Example

Toggles between 1–variable and 2–variable statistics in the Statistics aplet. Does not appear in the Plot Setup input form. Corresponds to the 9$5aand 9$5amenu keys in Numeric View.
