The following is the meaning of each item in the case of list data specification.
How Many ................... selects One-Way ANOVA or Two-Way ANOVA (number of lev-
els).
Factor A ....................... category list.
Dependnt .................... list to be used for sample data.
Save Res .................... first list for storage of calculation results.
Execute ....................... executes a calculation or draws a graph (Two-Way ANOVA only)
The following item appears in the case of Two-Way ANOVA only.
Factor B ...................... category list.
After setting all the parameters, align the cursor with [Execute] and then press one of the
function keys shown below to perform the calculation or draw the graph.
•
1
(CALC) ... Performs the calculation.
•
6
(DRAW) ... Draws the graph (Two-Way ANOVA only).
Calculation results are displayed in table form, just as they appear in science books.
# [Save Res] saves each vertical column of the
table into its own list. The leftmost column is
saved in the specified list, and each
subsequent column to the right is saved in
the next sequentially numbered list. Up to five
lists can be used for storing columns. You
can specify an first list number in the range of
1 to 16.
