Yates' correction for continuity should be applied when cell frequencies are small and 2x2 tables are used in the chi-square test. It adjusts the value of chi-square to account for the fact that the chi-square distribution is continuous, while the data is discrete. Using a different value for the expected or observed frequencies would not be appropriate in this situation.
