Quizplus · Accepted Answer

The unbiased estimator of the population variance represents the variability in the data that is not explained by the treatment or other variables. This is often referred to as the "error" or "noise" component in the t test. The population variance and standard deviation are measures of variability in the population, but they are not used directly in the t test. Similarly, the estimator of the population standard deviation is not used in the t test.
