Sentence examples for variance of means from inspiring English sources

It is defined as the variance of means (between class) / mean of variances (within class).

Finally, since the QP used by H.264 is designed to change the quantization step size and the relationship between the QPs is well defined, this relationship can be used to adjust the thresholds of the statistics (residual, variance of means, means of variance, etc).

To detect a difference between the three groups (hypothalamic impairment vs. pituitary insufficiency without hypothalamic impairment vs. healthy controls) with significance level α = 0.05, power = 80%, variance of means = 0.019, and a common standard deviation = 0.16, we needed six subjects per group (used software: nQuery Advisor 7.0, 1995–2007, developed by Janet D. Elashoff).
