Performing a one-sample hypothesis test

Test if the mean/median/variance of a distribution is different 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.
