ANOVA power dialog for a nested-factorial design
This GUI (separate window) may be used to study power and sample-size
problems for a nested factorial design in two primary factors
wp (the whole-plot or between-subjects factor)
and sp (the subplot or within-subjects factor).
PLOT is nested in wp and is considered a random factor.
This design is sometimes called a split-plot design with a completely
randomized design on the whole plots. If the whole-plot factor wp
is run in blocks, see the applet for a
"split-plot" design.
Click or drag on the bar graphs to adjust values; or
enter values in the text areas and hit RETURN. (Power
values are not adjustable.) You can change the scales for
the bar graphs by dragging from any point along the scale to
its desired new position -- provided that this would not
cause a bar to go out-of-bounds.
