**Explain CHI-SQUARE TEST:** Chi (pronounced like “pie” but beginning with a “k”) is a Greek letter, and chi-square is “a statistical method used to test whether the classification of data can be ascribed to chance or to some underlying law.”[websters] The chi-square test “is an analysis technique used to estimate whether two variables in a cross tabulation are correlated.”[shin] A chi-square distribution varies from normal distribution based on the “degrees of freedom” used to calculate it. See also normal distribution and Wikipedia on the chi-squared test and on chi-squared distribution..
