Once you have calculated the test statistic, you would need to use a computer or a chi-square table to find the approximate P value. While this can be done by hand, there are several opportunities for human error, which is why we recommend this calculator (or Prism for more advanced anal...
or using a calculator, using chi-square tests. But the chi-square test is only an approximation. The Yates' continuity correction is designed to make the chi-square approximation better, but it overcorrects so gives a P value that is too large (too 'conservative'). With large sample...
