Chi-squared test

  • abstract: Preface: The Chi-Square distribution is the distribution of the sum of the squares of a set of normally distributed random variables. Its value stems from the fact that the sum of random variables from any distribution can be closely approximated by a normal distribution as the sum as samples size increases.
