Variance/Mean Ratio Test:
The variance/mean ratio (VMR) test is a statistical test used to test the null hypothesis that the variance/mean ratio is 1.0.
The VMR test is usually dealt with as a one-sided test because each direction of departure from the null hypothesis has a radically different meaning in the context of a real problem (see properties of the variance/mean ratio ).
Planning on taking an introductory statistics course, but not sure if you need to start at the beginning? Review the course description for each of our introductory statistics courses and estimate which best matches your level, then take the self test for that course. If you get all or almost all the questions correct, move on and take the next test.
