This is going to be a long video, so be sure to pause when you need to do so!

I talk about how to find the probability of a sample mean using the z-score for sample means formula and the Unit Normal Table.

I talk about how to calculate the standard error.

I talk about the basic concepts behind the sampling distribution.

I do some more examples for finding the probability/proportion of scores in the normal distribution.

I show how to find the probability of an X-value in a population.

In this video, I discuss Chapter 5, z-scores.

In this video, I do a quick review of graphs from Chapter 2 and an overview of Chapter 3 and 4.

I discussion questions 17-26 on the review. These questions cover Chapters 5, 6, and 7.

This video covers final exam review questions 1-16, which cover Chapters 1, 2, 3, and 4.

I show examples of finding the probability of an X value in a population

I explain estimated Cohen's d and percentage of variance explained for the single-sample t-test. I also say "so" a lot. :)

I start a demo of a hypothesis test of the single-sample t-test.
