With Two-Way ANOVA, you can draw Interaction Plot graphs. The number of graphs depends
on Factor B, while the number of X-axis data depends on the Factor A. The Y-axis is the
average value of each category.
You can use the following graph analysis function after drawing a graph.
• 1(Trace) or !1(TRCE) ... Trace function
Pressing d or e moves the pointer on the graph in the corresponding direction. When there
are multiple graphs, you can move between graphs by pressing f and c.
• Graphing is available with Two-Way ANOVA only. V-Window settings are performed
automatically, regardless of Setup screen settings.
• Using the Trace function automatically stores the number of conditions to alpha variable A
and the mean value to variable M, respectively.
