Input Data Form

Raw Data

Enter column with range format. For help with range controls, see: Specifying Your Input Data

Input

Enter the input data.

Test Mean	The hypothetical mean to be tested. When you enter a value, null and alternate hypotheses are adjusted accordingly.
Null Hypothesis	The null hypothesis to be tested. (Mean = Test Mean)
Alternate Hypothesis	The alternate hypothesis. Options: Mean <>Test Mean Used for two-tailed test. Test whether the sample mean differs from the hypothesized mean. Mean >Test Mean Used for upper-tailed test. Test whether the sample mean is greater than the hypothesized mean. Mean <Test Mean Used for lower-tailed test. Test whether the sample mean is less than the hypothesized mean.
Significance Level	Specify a significance level.
Confidence Interval(s)	Compute confidence interval for the mean. For computation details, see Algorithms (One-Sample T-Test).
Confidence Level(s) in %	Specify space-separated confidence levels, (1- $\sigma$ )%. Available when Confidence Interval(s) is selected.

Actual Power	Compute the power of the test (the probability of rejecting the null hypothesis when it is false).
Significance Level	Only available when Hypothetical Power and/or Actual Power are checked. This is the significance level (alpha value) for power computation.
Hypothetical Power	Compute the power of the test at various sample sizes.
Hypothetical Sample Size(s)	Only available when Hypothetical Power is checked. Specify hypothetical sample size(s) for power computation.

Box Chart	Plot a box chart.
Histogram	Plot a histogram.
Arrange Plots of Same Type in One Graph	Note that for histograms, the layers will be arranged vertically. For box charts, layers will be arranged horizontally.

For help with the range controls, see: Output Results

Results Log Output	Select to output results to the Results Log.
Output Plot Data	Specify a worksheet for output of plotted data (Origin generates tabular data when plots are created). This item is only available when the Input Data Form is Raw.
Output Results	Specify the worksheet for output of test results.
