How it works: The calculator above takes the place of the traditional textbook table. First, enter the appropriate number of degrees of freedom in the top box. Then, the calculator can be used in two ways. To find chi square critical values, enter a probabilitiy in the "=" box and hit "Compute!". Use McNemar's test (and this calculator) only when you are analyzing matched pairs. Each value you enter above represents a number of PAIRS. The total number of subjects in the study is twice the total of the values you enter above. Note that the calculations are based entirely on the first two numbers you enter. Enter the remaining two numbers ...

I need help on using a particular applet I am willing to provide minimal support if you truly don’t understand what inputs are required. However, each applet has a help menu, and I do request that you carefully read that before you e-mail me with questions. Also, this is getting to be pretty old software. Nothing has really changed here in a ...

There are three ways to compute a P value from a contingency table. Fisher's test is the best choice as it always gives the exact P value, while the chi-square test only calculates an approximate P value. Only choose chi-square if someone requires you to. The Yates' continuity correction is designed to make the chi-square approximation better ...
