Power Analysis of OneSample T Test: Plot
The Plot dialog provides options for controlling 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 sample size
 When enabled, this optional setting provides options for controlling the twodimensional 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 twodimensional 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 twodimensional 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 twodimensional 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 twodimensional power by effect size chart. The value must be greater than the Lower bound value and cannot be greater than 5.0.
 ThreeDimensional Plot

 Power estimation versus
 Provides options for controlling the threedimensional power by sample size (xaxis) and effect
size (yaxis) 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 xaxis and sample size on yaxis
 The optional setting controls the threedimensional power by sample size (xaxis) and effect size (yaxis) chart. By default, the chart is suppressed. When specified, the chart displays.
 Effect size on yaxis and sample size on xaxis
 The optional setting controls the threedimensional power by sample size (yaxis) and effect size (xaxis) 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 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.
 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 threedimensional 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 threedimensional 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 threedimensional 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 threedimensional power by effect size chart. The value must be greater than the Lower bound value and cannot be greater than 5.0.
