Performing a one-sample hypothesis test

Test if the mean/median/variance of a distribution is equal to the hypothesized value.

  1. Select a cell in the dataset.
  2. On the Analyse-it ribbon tab, in the Statistical Analyses group, click Distribution, and then click the hypothesis test.
    The analysis task pane opens.
  3. In the Y drop-down list, select the variable.
  4. In the Hypotheses drop-down list, select the null and alternative hypothesis.
  5. In the Hypothesized value edit box, type the expected value of the parameter under the null hypothesis.
  6. Optional: To compare the p-value against a predefined significance level, in the Significance level edit box, type the maximum probability of rejecting the null hypothesis when in fact it is true (typically 5% or 1%).
  7. Click Calculate.
