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).

Central Limit Theorem

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).

Psychology Studies Biased Toward Western Undergraduates

Podcast describes that meta-analysis of scientific data show that top psychology research studies tend to make conclusions about human nature based on samples taken solely from Western undergraduate students (2:18).

What You Didn’t Know about the Stanford Prison Experiment

Describes the Stanford Prison Experiment and the flaws in the experiment (10:15).
