As you know, there is a whole family of \(t\)-distributions, each one specified by a parameter called the degrees of freedom, denoted \(df\). Similarly, all the chi-square distributions form a family, and each of its members is also specified by a parameter \(df\), the number of degrees of freedom.

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.
