Then, a table displays the results including the biserial correlation and p-value of the test. The first table corresponds to basic summary statistics for the various input variables. Interpreting the results of a biserial correlation analysis In the options tab we choose to test whether the biserial correlation is different from 0 or not using the Monte Carlo method.Īfter you have clicked on the OK button, the computations start and the results are displayed. Once you have clicked on the button, the dialog box appears. Once XLSTAT-Pro is activated, select the Describing data / Biserial correlation, or click on the corresponding button of the Describing data toolbar. Setting up a biserial correlations analysis The biserial correlation is useful to evaluate the degree of association between a binary (or dichotomous) variable and a continuous variable. The variance is assumed to be the same whatever the group to which an observation belongs. The biserial correlation requires that we have one binary variable and one continuous variable. We want to use the biserial correlation to check whether there is an association between the concentration and the species.
