Document Summary

The distribution of a sample mean: mean and variance. This section involves getting comfortable with the sampling distribution of the mean app that they link in the first part of the module. The most recent trial graph plots the probability density function (black curve) describing the individual measurements with randomly generated observations (blue points) and the sample mean of these observations (blue bar) The observed sample means histogram plots each random sample of observations. Every study that is carried out should be viewed as a single outcome from a population of studies that could have been performed under the same conditions. The sample size per trial toggle refers to the number of sample observations generated when clicking on the generate samples button. The skew toggle controls how right or left-skewed (dependent on if positive or negative) the probability distribution of the measurement is; 0 indicates symmetry.
