k Displaying the Calculation Results of a Drawn Paired-Variable Graph
Paired-variable statistics can be expressed as both graphs and parameter values. When
these graphs are displayed, the paired-variable calculation results appear as shown below
when you press 4(CALC)b(2VAR).
•Use c to scroll the list so you can view the items that run off the bottom of the screen.
o ............... mean of data stored in xList
Σx ............. sum of data stored in xList
