Supporting Information

Select check box to output results to the Results Log.

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

Null Mean	The presumed mean under the null hypothesis.
Alternative Mean	The mean proposed by the alternative hypothesis.
Standard Deviation	Sample standard deviation.
Alpha	The probability of rejecting the null hypothesis when it is true.
Hypothetical Power(s)	Specify spaced-separated list of hypothetical power(s). Available when Calculate = Sample Size.
Hypothetical Sample Size(s)	Specify spaced-separated list of hypothetical sample size(s). Available when Calculate = Power.
Alternative Hypothesis	Select a Alternative Hypothesis for your one-sample t-test. Not Equal Perform a 2-sided test for tail. Used to test Alternative Mean is significantly different from Null Mean . Greater than Perform a right-tailed test. (When Calculate is set to Sample Size, Alternative Mean should be greater than Null Mean for a Greater than Alternative Hypothesis.) Less than Perform a left-tailed test. (When Calculate is set to Sample Size, Alternative Mean should be less than Null Mean for a Less than Alternative Hypothesis.)

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.
