Degrees of freedom in a Chi-square test refers to the number of observations that are free to vary after certain constraints have been imposed. In a contingency table, degrees of freedom are calculated by subtracting one from both the number of rows and the number of columns, and then multiplying the results. This yields the total number of degrees of freedom for the table.
