What Does It “Mean”? A Review of Interpreting and Calculating
... logarithm of the ratio of test AUC/reference AUC (i.e., the difference in natural log (Ln)-transformed AUC values) is subsequently calculated for each study subject. The mean and residual error (variance) of the within subject test/reference product ratios are determined. On the basis of these stati ...

... In a certain factory there are two independent processes manufacturing the same item. The average weight in a sample of 250 items produced from one process is found to be 120 Ozs, with a s.d of 12 Ozs, while the corresponding figures in a sample of 400 items from the other process are 124 Ozs and 14 ...

The Sampling Distribution of the Mean
... To define some terms, if samples from a population are labeled with the variable X, we define the parameters of mean as µx and the standard deviation as σx . Remember, the greek letter is the parameter, and the subscript is the name of the thing that we’re talking about. Now consider the sampling di ...
