WebThe statistical test for correlation uses a null hypothesis that the correlation is 0, which would indicate no correlation, so a P value less than the cutoff threshold indicates evidence that the variables are correlated. Enter any number for r between -1 and 1 and the degrees of freedom (which is n-2) for your study to calculate the P value ... WebOne-Way Chi-Square. Chi-Square "Goodness of Fit" Test. The logic and computational details of chi-square tests. are described in Chapter 8 of Concepts and Applications. This unit will calculate the value of chi-square for a one-dimensional "goodness of fit" test, for up to 8 mutually exclusive categories labeled A through H.
