Continuity adjusted chi-square
WebDetermining the Critical Value for a Chi-Square Distribution (X R 2 (X_R^2 (X R 2 and X L 2) X_L^2) X L 2 ) If a Chi-Squared distribution has 8 degrees of freedom find X R 2 … Using the chi-squared distribution to interpret Pearson's chi-squared statistic requires one to assume that the discrete probability of observed binomial frequencies in the table can be approximated by the continuous chi-squared distribution. This assumption is not quite correct, and introduces some error. To reduce the error in approximation, Frank Yates, an English statistician, suggested a correctio…
