How many degrees of freedom in a 3 x 4 table

WebApr 12, 2024 · The computation of the degrees of freedom is: degrees of freedom = (number of rows - 1) x (number of columns -1) degrees of freedom = (3-1) x (3-1) degrees of freedom = (2) x (2) degrees of freedom = 4 and the "chi-square critical value” for degrees of freedom of "4” at p<0.05 = 9.49 WebThat means you used 5-1 = 4 degrees of freedom in computing the expected value. Because there are 6 observations, you only have 6 - 4 = 2 degrees of freedom left. Note how your method of placing all the data into a single column obscures the information about degrees of freedom, whereas the standard tabular layout implicitly gives this information.
