Chi-squared distribution, showing χ2 on the x -axis and p -value (right tail probability) on the y -axis. A chi-squared test (also chi-square or χ2 test) is a statistical hypothesis test used in the analysis of contingency tables when the sample sizes are large. In simpler terms, this test is primarily used to examine whether two categorical ...

Alpha Phi Alpha Fraternity, Inc. ( ΑΦΑ) is the oldest intercollegiate historically African American fraternity. It was initially a literary and social studies club organized in the 1905–1906 school year at Cornell University but later evolved into a fraternity with a founding date of December 4, 1906. It employs an icon from Ancient Egypt ...
Website. chiphi .org. Chi Phi ( ΧΦ) is considered by some as the oldest American men's college social fraternity that was established as the result of the merger of three separate organizations that were each known as Chi Phi. The earliest of these organizations was formed at Princeton University in 1824.

The Pearson's chi-squared test statistic is defined as . The p-value of the test statistic is computed either numerically or by looking it up in a table. If the p-value is small enough (usually p < 0.05 by convention), then the null hypothesis is rejected, and we conclude that the observed data does not follow the multinomial distribution.
In statistics, the phi coefficient (or mean square contingency coefficient and denoted by φ or r φ) is a measure of association for two binary variables.. In machine learning, it is known as the Matthews correlation coefficient (MCC) and used as a measure of the quality of binary (two-class) classifications, introduced by biochemist Brian W. Matthews in 1975.
