3 0/ 1 point The Yates correction for Chi square is used when: The contingency table is 2 x 2. Any proportion is less than 0.5. X O The expected value for any cell is less than five. On is greater than 50. 4 0/ 1 point The Yates correction for Chi square is best described as: Addition of a small factor to inflate the value of x2. X Subtraction of 1/2 x (1j + 12) from the magnitude of the difference of proportions. Subtraction of 0.5 from the magnitude of the difference between the observed count and the expected count for each term in X2. )A way to adjust for very small n
