Select the box to output results to Results Log (in addition to that specified in Output Results).


Power Compute power for specified sample size.
Sample Size Compute sample size for proposed power.

Test Specification

Null Proportion Value against which the alternate proportion is tested.
Alternate Proportion Value of the hypothesized proportion.
Alpha Probability of rejecting the null hypothesis when it is true.
Hypothetical Power(s) Specify space-separated list of hypothetical power(s). Available when Calculate = Sample Size.
Hypothetical Sample Size(s) Specify space-separated list of hypothetical sample size(s). Available when Calculate = Power.
Alternative Hypothesis

Perform a one- or two-sided test:

Not Equal
Indicates that the two-tail proportion test is used.
Less Than
Indicates that the lower-tail proportion test is used.
Greater Than
Indicates that the upper-tail proportion test is used.


Controls to be used when supplying additional power or sample size values by worksheet dataset:

When calculating power (Calculate = Power):

More Hypothetical Sample Size(s) Select to activate the Hypothetical Sample Size(s) Column input controls.
Hypothetical Sample Size(s) Column Specify column of sample size values. Available when More Hypothetical Sample Size(s)... is selected.

When calculating power (Calculate = Sample Size):

More Hypothetical Power(s) Select to activate the Hypothetical Power(s) Column input controls.
Hypothetical Power(s) Column Specify column of power values. Available when More Hypothetical Power(s)... is selected.

Power Curve

Select to output power curves. The power curve plots every combination of power v.s. the Alternative Proportion. Power curves are helpful for determining the appropriate sample size or power for the test.
