Power Analysis of One-Sample T Test: Plot
The Plot dialog provides options for controlling 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 sample size
- When enabled, this optional setting provides options for controlling the two-dimensional power
by sample size chart. The setting is disabled by default.
- Range of 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 two-dimensional power by sample size chart. The value must be greater than 1, and cannot be greater than the Upper bound value.
- Upper bound
- Controls the upper bound for the two-dimensional power by sample size chart. The value must be greater than the Lower bound value and cannot be greater than 5000.
- Power estimation versus effect size
- By default, this optional setting is disabled. 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 effect size used.
- Range of effect size
- When selected, the lower and upper bound options are available.
- Lower bound
- Controls the lower bound for the two-dimensional power by effect size chart. The value must be greater than, or equal to, -5.0 and cannot be greater than the Upper bound value.
- Upper bound
- Controls the upper bound for the two-dimensional power by effect size chart. The value must be greater than the Lower bound value and cannot be greater than 5.0.
- Three-Dimensional Plot
-
- Power estimation versus
- Provides options for controlling the three-dimensional power by sample size (x-axis) and effect
size (y-axis) chart, the vertical/horizontal rotation settings, and the user specified plot range of
sample/effect size. This setting is disabled by default.
- Effect size on x-axis and sample size on y-axis
- The optional setting controls the three-dimensional power by sample size (x-axis) and effect size (y-axis) chart. By default, the chart is suppressed. When specified, the chart displays.
- Effect size on y-axis and sample size on x-axis
- The optional setting controls the three-dimensional power by sample size (y-axis) and effect size (x-axis) chart. By default, the chart is suppressed. When specified, the chart displays.
- 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.
- Range of 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 sample size chart. The value must be greater than 1, and cannot be greater than the Upper bound value.
- Upper bound
- Controls the upper bound for the three-dimensional power by sample size chart. The value must be greater than the Lower bound value and cannot be greater than 5000.
- 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 effect size chart. The value must be greater than, or equal to, -5.0 and cannot be greater than the Upper bound value.
- Upper bound
- Controls the upper bound for the three-dimensional power by effect size chart. The value must be greater than the Lower bound value and cannot be greater than 5.0.
