WebZ-scores generally ranges from -3.99 to 0 on the left side and 0 to 3.99 on the right side of the mean. Refer the column & row values for z-score. The point where the row & column meets for the corresponding z-score value is the critical value of Z or the rejection area of one or two tailed z-distribution. WebFeb 22, 2015 · The value that defines the starting of that rejection zone is the critical value. For instance, in a two-tailed test, the critical value for 95% is 1.96 (which means if your observed z-score is bigger than 1.96 or smaller than -1.96 you'll reject the null.) For one-tailed, it'd be 1.64 at the right OR -1.64 at the left.
