Khan Academy: Sampling Distribution: Standard Error of the Mean

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. Uses the...

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.

There's absolutely no error in using the tutorial! Learners use spreadsheets to create column or bar graphs with error bars. They also learn how to calculate the standard error of the mean in the tutorial. This is the third installment...

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

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

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.

In this video, a simulation is used to demonstrate the sampling distribution of sample proportions. [4:34]

Standard error means ... it's okay to be wrong? Viewers learn how to calculate standard error from the standard deviation and the number of data values, both by hand and by using spreadsheets. The video also shows how to display this...

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.
