Chi-Squared test calculator

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. http://www.jtrive.com/goodness-of-fit-and-significance-testing-for-logistic-regression-models.html gary hazen lake ariel paWebThe meaning of GOODNESS OF FIT is the conformity between an experimental result and theoretical expectation or between data and an approximating curve. gary hazelton bemidji
