WebIn probability theory and statistics, the chi-squared distribution (also chi-square or -distribution) with degrees of freedom is the distribution of a sum of the squares of independent standard normal random variables. The chi-squared distribution is a special case of the gamma distribution and is one of the most widely used probability … WebIn "Contigency table chi-square test", the degree of freedom in completely different because our data is measured along two axes (type of drug and cured/sick). For a contingency table, the degree of freedom is (r - 1) * (c -1) where r is the number of rows and c is the number of columns.
