How to do a chi-square test with Yates correction with R

WebA continuity correction applied to a chi-squared contingency table test. Normally only applied for a 2×2 table, where the effect is greatest and by a happy coincidence the arithmetic required is the simplest. It involves diminishing the numerical size of the difference between observed and expected values by 0.5 before squaring, i.e. the chi-square … WebH0, based on the chi square table, because at the .05 level, this value is in the critical region. That is, a chi square distribution with df = 1 only has 5% (i.e., .05) of values that are larger than 3.84, which is what we have obtained.

R can also perform a chi-square test on frequencies from a contingency table.

This reduces the chi-squared value obtained and thus increases its p-value. The effect of Yates's correction is to prevent overestimation of statistical significance for small data. This formula is chiefly used when at least one cell of the table has an expected count smaller than 5.
