Sampling Distributions: Introduction to the Concept
Video describes sampling distribution and statistical inference. Illustrates sampling distribution of the sample mean in a simple example (7:51).
Sampling Distribution of the Mean
Video describes important properties of the sampling distribution of the mean and variance (5:26).
Proof that the Sample Variance is an Unbiased Estimator of the Population Variance
Describes why the sample variance is an unbiased estimator of the population variance (6:57).
This provides a video on central limit theorem, an article describing the concept, and a simulation to demonstrate the effect of sample size on the shape of the sampling distribution of the mean (:27).
