You can use the following graph analysis functions after drawing a graph.
• 1(F) ... Displays F value.
Pressing 1(F) displays the F value at the bottom of the display, and displays the pointer at the
corresponding location in the graph (unless the location is off the graph screen).
Two points are displayed in the case of a two-tail test. Use d and e to move the pointer.
Press J to clear the F value.
• 2(P) ... Displays p-value.
Pressing 2(P) displays the p-value at the bottom of the display without displaying the pointer.
Press J to clear the p-value.
