Degrees of freedom (df) represent the number of scores that can vary without changing the value of a statistic we already know. This is important in the chi-square test, as it helps to determine the critical value needed to reject the null hypothesis. In general, the higher the df, the wider the range of possible values for the test statistic and the less confident we can be in rejecting the null hypothesis.
