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://mathcracker.com/chi-distribution-calculator

Chi Square: Degrees of freedom: p : Fill in the fields for Chi Square and … In inferential statistics, you estimate a parameter of a population by calculating a statistic of a sample. The number of independent pieces of information used to calculate the statistic is called the degrees of freedom. The degrees of freedom of a statistic depend on the sample size: 1. When the sample size is … See more The degrees of freedom of a test statistic determines the critical value of the hypothesis test. The critical value is calculated from the null distribution and is a cut-off value to decide whether to reject the null hypothesis. … See more The degrees of freedom of a statistic is the sample size minus the number of restrictions. Most of the time, the restrictions are parametersthat are estimated as intermediate steps in calculating the … See more

WebThe chi-square test of independence determines whether there is a statistically significant relationship between categorical variables in a table. Just like other hypothesis tests, this test incorporates DF. To find the chi-square DF for a table with r rows and c columns, use this formula to calculate degrees of freedom: (r-1) (c-1).
