Webto adjust them to minimize the chi-square. The number of parameters you adjusted has to be subtracted from the degrees of freedom. Classes with expectations less than 1 should be combined – th ey may cause inaccuracy of the chi-square approximation. The degrees of freedom is correspondingly reduced.

In table 8.1 for sample A this is 155/289 = 0.5363. This fraction is then successively multiplied by 22, 46, 73, 91, and 57. For sample B the fraction is 134/289 = 0.4636. imagine cinemas market square showtimesWebStep 3: Use the Critical Values Table to Determine the Probability (p) Value of getting the sum Chi-square value by chance.
