When doing a 2 by 2 chi square, when any expected frequency is less than 10, the Yates correction suggests that the researcher should
A) reduce the fo-fe value by .5
B) increase the fe by .5
C) reduce the fe by .5
D) not calculate a chi square because of the small fe

The Yates correction for continuity (or Yates' chi-squared test) suggests that the researcher should adjust the formula by reducing the absolute difference between the observed frequency (fo) and the expected frequency (fe) by 0.5. This correction is applied to prevent overestimation of statistical significance for small sample sizes in a 2x2 chi-square test.
