# 17.3.1.1 The One-Sample T-Test Dialog Box

## Supporting Information

To open the One-Sample t-Test dialog box:

1. With a worksheet active, click Statistics: Hypothesis Testing: One-Sample t-Test...

## Recalculate

Recalculate Controls recalculation of analysis results None Auto Manual For more information, see: Recalculating Analysis Results

## Input

Input Data Form Summarized Data Enter value of mean, standard deviation and sample size data for sample(s), in the form as "mean SD N" (space separated numbers) Raw Data Enter column with range format. For help with range controls, see: Specifying Your Input Data Enter the input data.

## t-Test for Mean

Test Mean The hypothetical mean to be tested. When you enter a value, null and alternate hypotheses are adjusted accordingly. The null hypothesis to be tested. (Mean = Test Mean) 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

## Power Analysis

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

## Plots

Box Chart Plot a box chart. Plot a histogram. Note that for histograms, the layers will be arranged vertically. For box charts, layers will be arranged horizontally.

## Output

For help with the range controls, see: Output Results

Results Log Output Select to output results to the Results Log. 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. Specify the worksheet for output of test results.
