Question: The chi square distribution is continuous whereas the test statistic used

The chi-square distribution is continuous, whereas the test statistic used in this section is discrete. Some statisticians use Yates’s correction for continuity in cells with an expected frequency of less than 10 or in all cells of a contingency table with two rows and two columns. With Yates’s correction, we replace
Given the contingency table in Example 4, find the value of the X2 test statistic using Yates’s correction. What effect does Yates’s correction have?
