The critical value separates the critical region from the noncritical region.  The symbol for critical value is C.V.


The critical or rejection region is the range of values of the test value that indicates that there is a significant difference and that the null hypothesis should be rejected.


The noncritical or non rejection region is the range of values of the test value that indicates that the difference was probably due to chance and that the null hypothesis should not be rejected.
