Testing correlation/association

Test if the correlation between 2 variables is equal to a hypothesized value, or test for independence.

  1. Select a cell in the dataset.
  2. On the Analyse-it ribbon tab, in the Statistical Analyses group, click Correlation, and then the parameter estimator.
    The analysis task pane opens.
  3. If analyzing two variables:
    1. In the Model drop-down menu, select Bivariate.
    2. In the X drop-down list, select the first variable.
    3. In the Y drop-down list, select the second variable.
  4. If analyzing more than two variables:
    1. In the Model drop-down menu, select Multivariate.
    2. In the Variables list, select the variables.
  5. Select the Hypothesis test check box.
  6. In the Hypotheses drop-down list, select the null and alternative hypothesis.
  7. 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%).
  8. Click Calculate.
