Statistics - One Question Hypothesis Testing

One-Question Hypothesis Testing enables you to determine whether a sample parameter has changed or differs from a particular value. This situation, deemed a one group test, allows you to compare the difference between your selected variable and a known value, which is zero by default or can be defined when you set up the test.

To perform a One-Question Hypothesis Test:

  1. Select Statistics One-Question Hypothesis Testing. The Hypothesis Testing: Single Question dialog box will appear.
  2. You can have a query applied for this test by choosing a query you have created and clicking on the query name in the Query listbox.
  3. Now choose the question you would like to test from the Question listbox. You should now see data in the Test Results box.
  4. The Stats checkbox determines whether or not the Mean, Cases count, and Std Error statistics are shown in the Test Results box.
  5. The value in the Hypothesis text box is the value being compared to and can be changed as desired.
  6. The Margin of Error checkbox determines whether or not the Lower limit, Mean, Upper limit and Confidence level statistics are shown in the Test results box.
  7. The value in the Confidence Level text box determines margin of error statistics and can be changed as desired.
  8. Be sure to click on your question in the Select Question box to refresh the data in the Test Results box after changing any of the options above.
  9. Click Finish when the results are displayed as you would like.
