WebTo calculate the degrees of freedom (df) for a Chi-Squared Test can be done as follows; For a two-way table. df = (m - 1) (n - 1) // where m = # of columns & n = # of rows. For a one way table. df = k - 1 // where k equals the number of groups. So in short, yes; in a one way table that deals with 2 groups will correspond to 1 degree (s) of freedom.
