Screenshot Statistics options for contingency table. After calculating the four chi squared term values for the four possible combinations they were summed to calculate the overall chi squared value in cell D20. Because this is a 2x2 contingency table the number of degrees of freedom is 1.
First row and column are row and column group identifiers. Returns the position of probability on the inverse cumulative gamma distribution with dof degrees of freedom. Calculate Cramers V which is a measure of the strength. These tables provide a foundation for statistical inference where statistical tests question the relationship between the variables on the basis of the data observed. And the groups have different numbers. 2 X 2 Contingency Table.
Or have you found something significant.
