Degree Of Freedom Chi Square Test. For example a biologist might want to determine if two species of organisms associate are found together in a community. A lot of statistics look like they are made up of many random variables say n of them. Chi-square tests are always right-tailed tests. The p-value can be found using Minitab.
For example a biologist might want to determine if two species of organisms associate are found together in a community. The degrees of freedom for the chi-square test statistic are rc - 1 - r-1 c-1 rc -1 - r 1 - c 1 rc - r - c 1 r - 1c - 1. Assessing the size of our obtained Chi-Square value. What you do in a nutshell. A lot of statistics look like they are made up of many random variables say n of them. The degrees of freedom in this case is r 1 c 1 where r is the number of rows number of different genes and c is the number of columns number of lists.

Chi-Square X2 Test for Independence. As stated by Jonathan Fivelsdal in his answer the degrees of freedom of a mathi times j mathcontingency table are given by mathi-1j-1math where mathimath is the number of rows and mathjmath is the number of columns. The table below can help you find a p-value the top row when you know the Degrees of Freedom DF the left column and the Chi-Square value the values in the table. The resulting figure is the degrees of freedom for the chi-square test. Or just use the Chi-Square Calculator. Degrees of Freedom is the number of classes or categories there are in the observations minus 1.
