Power Analysis of One-way ANOVA: Plot
The Plot dialog controls the plots that are output to illustrate the two and three-dimensional power by sample and effect size charts. The dialog also controls the vertical and horizontal rotation degrees for three-dimensional charts.
- Two-Dimensional Plot
-
- Power estimation versus total sample size
- When enabled, this optional setting provides options for controlling the two-dimensional 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 two-dimensional 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 two-dimensional 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 two-dimensional 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 two-dimensional 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 two-dimensional power by pooled standard deviation chart. The value must be greater than the Lower bound value.
- Three-Dimensional Plot
-
- Power estimation versus
- Provides options for controlling the three-dimensional power by total sample size (x-axis) and
effect size (y-axis) 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 x-axis and total sample size on y-axis
- The optional setting controls the three-dimensional power by total sample size (x-axis) and pooled standard deviation (y-axis) chart. By default, the chart is suppressed. When specified, the chart displays.
- Pooled standard deviation on y-axis and total sample size on x-axis
- The optional setting controls the three-dimensional power by total sample size (y-axis) and pooled standard deviation (x-axis) 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 three-dimensional 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 three-dimensional 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 three-dimensional 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 three-dimensional 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 three-dimensional 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 x-axis and total sample size on y-axis
- The optional setting controls the three-dimensional power by total sample size (x-axis) and effect size (y-axis) chart. By default, the chart is suppressed. When specified, the chart displays.
- Pooled standard deviation on y-axis and total sample size on x-axis
- The optional setting controls the three-dimensional power by total sample size (y-axis) and effect size (x-axis) 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 three-dimensional 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 three-dimensional 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 three-dimensional 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 three-dimensional 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 three-dimensional chart. You can use the mouse to rotate the chart vertically. The setting takes effect when the three-dimensional 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 three-dimensional chart. You can use the mouse to rotate the chart horizontally. The setting takes effect when the three-dimensional plot is requested. The value must be a single integer value less than or equal to 359. The default value is 325.
