WebThis unit will calculate the value of chi-square for a one-dimensional "goodness of fit" test, for up to 8 mutually exclusive categories labeled A through H. To enter an observed cell frequency, click the cursor into the appropriate cell, then type in the value. Expected values can be entered as either frequencies or proportions. WebTo get more technical: - An F distribution is the ratio of two Chi-square variables, each of which is divided its respective degrees of freedom. So (C1/c1) / (C2/c2), where the …
