Summary
In order to compare the precision (expresed by the variance) of a new measurement method with that of a traditional measurement method the null hypothesis of equality of the two variances can be tested with a one-sided F-test. A sequential Wald test is proposed as an alternative, and its operating characteristic function is investigated by means of a simulation study. This study shows that the test can be ended with twice the sample size of the corresponding F-test without a substantial change of the operating characteristic function.
