It is probably familiar to think about the standard deviation of the estimates of the potency (or log potency; for the rest of this discussion we will work with log potency) from several plates within a day. The first variance component is then the variation in ...

Chapter 7 Inferences Based on a Single Sample: Estimation
... Definition 7.2 Point Estimator: A point estimator of a population parameter is a rule that tells you how to use the sample data to calculate a single number that can be used as an estimate of the population parameter. For example, the sample mean x̄ is a point estimator for the population mean μ. Defi ...

Review of Confidence Interval Concepts
... A confidence interval is an interval of values that is likely to "capture" the unknown value of a population parameter of interest, such as the true population mean, μ, or the true difference, μd. Another concept is to estimate the difference between two independent samples. However, we will save ...
