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. |
| Null Variance | Value of the true population variance. |
|---|---|
| Alternate Variance | Value of the hypothesized variance. |
| 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:

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 sample size (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. |
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.
