WebA chi-squared test (symbolically represented as χ 2) is basically a data analysis on the basis of observations of a random set of variables.Usually, it is a comparison of two statistical data sets. This test was introduced by Karl Pearson in 1900 for categorical data analysis and distribution.So it was mentioned as Pearson’s chi-squared test..
