A Gentle Introduction to the One Sample z Test (9-7)
Now it is time for our first real inference test (i.e. “hypothesis test”). We will use a one-sample z test to determine whether a sample mean is significantly different than the population mean when the standard deviation of the population is known. I use an example about the average age o

A Gentle Introduction to z Scores (9-1)
A z score tells you how far a raw score deviates from the mean when measured in standard deviation units. There are two parts to a z score: the number and a sign. The sign tells you whether the z score is above or below the mean. The number tells distance between the score and mean in term

How to do a One Sample z Test by Hand (9-8)
We are learning how to do a one-sample z test by hand. In the previous video, we walked through the first three steps of hypothesis testing, selecting a test, establishing the null and alternative hypotheses, and determining the critical value. Now we are ready to calculate the statistics.

Step 1 – Select the Appropriate Statistic (8-5)
The first step of hypothesis testing is to select the appropriate statistic for testing your hypothesis. You will make this decision based upon your data. Once you have chosen the analysis that you will use, that will determine how you will do each of the subsequent steps. This is both the
