Power Analysis of Oneway ANOVA: Plot
The Plot dialog controls the plots that are output to illustrate the two and threedimensional power by sample and effect size charts. The dialog also controls the vertical and horizontal rotation degrees for threedimensional charts.
 TwoDimensional Plot

 Power estimation versus total sample size
 When enabled, this optional setting provides options for controlling the twodimensional power
by total sample size chart. The setting is disabled by default.
 Range of total sample size
 When selected, the lower and upper bound options are available. When no integer values are
specified for the Lower bound or Upper bound fields,
the default plot range of the total sample size is used.
 Lower bound
 Controls the lower bound for the twodimensional power by total sample size chart. The value
must be greater than, or equal to:
 2 x the number of integers specified for Group sizes
 2 x the sum of the integers specified for Group sizes / by the smallest integer value for Group sizes
 Upper bound
 Controls the upper bound for the twodimensional power by total sample size chart. The value
must be less than, or equal to:
 5000 / by the largest integer value specified for Group sizes x the sum of the integers specified for Group sizes
 Power estimation versus pooled standard deviation
 By default, this optional setting is disabled. The setting controls the twodimensional power by
pooled standard deviation chart. When enabled, the chart displays in the output. When no integer
values are specified for the Lower bound or Upper
bound fields, the default plot range of the pooled standard deviation is used.Note:
The plot is disabled when the specified Group means values are all the same.
 Range of pooled standard deviation
 When selected, the lower and upper bound options are available.
 Lower bound
 Controls the lower bound for the twodimensional power by pooled standard deviation chart. The value must be greater than 0 and cannot be greater than the Upper bound value.
 Upper bound
 Controls the upper bound for the twodimensional power by pooled standard deviation chart. The value must be greater than the Lower bound value.
 ThreeDimensional Plot

 Power estimation versus
 Provides options for controlling the threedimensional power by total sample size (xaxis) and
effect size (yaxis) chart, the vertical and horizontal rotation settings, and the user specified
plot range of sample and effect size. This setting is disabled by default. Note:
The plot is disabled when the specified Group means values are all the same.
 Pooled standard deviation on xaxis and total sample size on yaxis
 The optional setting controls the threedimensional power by total sample size (xaxis) and pooled standard deviation (yaxis) chart. By default, the chart is suppressed. When specified, the chart displays.
 Pooled standard deviation on yaxis and total sample size on xaxis
 The optional setting controls the threedimensional power by total sample size (yaxis) and pooled standard deviation (xaxis) chart. By default, the chart is suppressed. When specified, the chart displays.
 Range of total sample size
 When selected, the lower and upper bound options are available. When no integer values are
specified for the Lower bound or Upper bound fields,
the default plot range of the sample size is used.
 Lower bound
 Controls the lower bound for the threedimensional power by total sample size chart. The value must be greater than 0 and cannot be greater than the Upper bound value.
 Upper bound
 Controls the upper bound for the threedimensional power by total sample size chart. The value must be greater than the Lower bound value.
 Range of pooled standard deviation
 When selected, the lower and upper bound options are available. When no integer values are
specified for the Lower bound or Upper bound fields,
the default plot range of the effect size is used.
 Lower bound
 Controls the lower bound for the threedimensional power by pooled standard deviation chart. The value must be greater than 0 and cannot be greater than the Upper bound value.
 Upper bound
 Controls the upper bound for the threedimensional power by pooled standard deviation chart. The value must be greater than the Lower bound value.
 Power estimation versus sample size
 Provides options for controlling the threedimensional power by effect size
and the user specified plot range of sample and effect size. This setting is disabled by default.
Note:
The plot is disabled when the specified Group means values are all the same.
 Pooled standard deviation on xaxis and total sample size on yaxis
 The optional setting controls the threedimensional power by total sample size (xaxis) and effect size (yaxis) chart. By default, the chart is suppressed. When specified, the chart displays.
 Pooled standard deviation on yaxis and total sample size on xaxis
 The optional setting controls the threedimensional power by total sample size (yaxis) and effect size (xaxis) chart. By default, the chart is suppressed. When specified, the chart displays.
 Range of total sample size
 When selected, the lower and upper bound options are available. When no
integer values are specified for the Lower bound or Upper
bound fields, the default plot range of the sample size is used.
 Lower bound
 Controls the lower bound for the threedimensional power by total sample size chart. The value must be greater than 0 and cannot be greater than the Upper bound value.
 Upper bound
 Controls the upper bound for the threedimensional power by total sample size chart. The value must be greater than the Lower bound value.
 Range of effect size
 When selected, the lower and upper bound options are available. When no
integer values are specified for the Lower bound or Upper
bound fields, the default plot range of the effect size is used.
 Lower bound
 Controls the lower bound for the threedimensional power by total sample size chart. The value must be greater than 0 and cannot be greater than the Upper bound value.
 Upper bound
 Controls the upper bound for the threedimensional power by total sample size chart. The value must be greater than the Lower bound value.
 Vertical rotation
 The optional setting sets the vertical rotation degrees (clockwise from the left) for the threedimensional chart. You can use the mouse to rotate the chart vertically. The setting takes effect when the threedimensional plot is requested. The value must be a single integer value less than or equal to 359. The default value is 10.
 Horizontal rotation
 The optional setting sets the horizontal rotation degrees (clockwise from the front) for the threedimensional chart. You can use the mouse to rotate the chart horizontally. The setting takes effect when the threedimensional plot is requested. The value must be a single integer value less than or equal to 359. The default value is 325.
