In order to ensure the reasonableness of the approximation, many statisticians recommend computing X2 only if most expected cell frequencies (say 80 percent) are greater than or equal to five. Although there is considerable controversy about the topic, this seems to be a safe rule that can be met in most situations where n is relatively large. Interpreting the Chi Square Test When we are told one baseball team defeated another, we usually want to know much more, such as the score, the winning and losing pitchers, and so forth.
On the one hand, they frequently have to analyze rather crudely measured data. Despite efforts to be as rigorous and precise as their colleagues in the natural sciences, they cannot quantify even some of the most important social and political concepts. Instead, they have to rely on rough and general category labels. On the other hand, they are called on to answer very sophisticated theoretical questions and to make exact predictions. It is as though a physicist were asked to construct a theory of heat but could only classify objects "hot" or "cold", instead of giving them a numerical temperature.
