This is the formula for Chi-Square: Χ 2 = Σ (O − E) 2 E. Σ means to sum up (see Sigma Notation) O = each Observed (actual) value; E = each Expected valu 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 The Chi Square Calculator then calculates the expected counts with what was actually observed. If the numbers are different by a large enough amount, Chi-Square determines that the groups do not have the same proportion. Requirements for a Chi Square Test: Data is typically attribute (discrete). All data must be able to be categorized as being.
