I talk about how to find the probability of a sample mean using the zscore 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 Xvalue in a population.


In this video, I discuss Chapter 5, zscores.


In this video, I do an overview of Chapter 1 and 2. I will cover graphs in Chapter 3 and 4 Overview. Thank you for your patience as you watch this video; my mind has been on other things lately as a…


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