17.9.1 (PSS) One-Sample T-Test

Use this feature to determine the power of a test given the sample size, or the sample size required to obtain a specified power for one-sample t-test.

Generally speaking, Power and Sample-Size tools can be used in two ways: sample-size estimation and power computation. The former can be used to determine the size of the sample to ensure a certain level of power when you are designing an experiment. The latter can be used to estimate the accuracy of the result after you have conducted an experiment on a specific number of samples.

To perform a Power and Sample Size for One-Sample t-Test:

  1. Select Statistics: Power and Sample Size: (PSS) One-Sample t-Test. This opens the PSS_tTest1 dialog box.
  2. From the Calculate list, choose Power or Sample Size, then choose your remaining options.
  3. Upon clicking OK, an analysis report sheet is generated.
