Khan Academy: Sampling Distribution of Sample Proportion Part 2

Formulas for the mean and standard deviation of a sampling distribution of sample proportions.

This video goes over the formulas for the mean and standard deviation of a sampling distribution of sample proportions. [9:56]

More on the Central Limit Theorem and the Sampling Distribution of the Sample Mean.

The central limit theorem and the sampling distribution of the sample mean.

Presents a problem that is similar to what might be on an AP Statistics exam. Walks students through each step for solving it and students input answers to questions along the way.

Watch a video to explore part 2 of Green's Theorem.

Video reviews the central limit theorem and uses a simulation to illustrate sampling distributions and how they approach a normal distribution with larger sample sizes even if the original distribution was not normal.

Video first briefly reviews the effect on the sampling distribution when the sample size increases then gives the formula for variance of the sample mean of the sampling distribution and formula for standard error of the mean.

Video discusses the effect of sample size on the sampling distribution.

Explains how to find the area of a Koch snowflake which is represented by an infinite geometric series. Continuation of previous video "Area of Koch Snowflake (part 1) - Advanced" [6:32]
