2.3: Chi-Square Test of Goodness-of-Fit - Statistics LibreTexts
WebThe phrase “goodness-of-fit” refers to the relationship between the observed sample distribution and the predicted probability distribution in the chi-square goodness-of-fit test. In other words, how well a theoretical distribution fits the empirical distribution is determined by the chi-square goodness-of-fit test. Recommended Articles 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. the lumineers imdb
