Statistics Lectures Now on YouTube!

Every semester, I try to upload my lectures to the University of South Alabama’s course management site, and, every semester, I run out of space before the half-way mark of the semester.  Our IT department recently recommended that I upload my videos to YouTube to avoid these space difficulties.  So, I am doing just that!

I already uploaded my first two lectures.  The first is a general review of statistics with a focus on descriptive statistics and p-values.  The second is an overview of one-variable chi-square tests and the chi-square test of independence (also called two-variable chi-square tests).  The links are provided below:

Chi-Square Test of Independence in Excel (Two Variable)

Just made a new guide as a follow-up to my prior guide!  It is on the chi-square test of independence, also known as the two-variable chi-square test.  Because the “Data Analysis” add-on in Excel does not have this function, it is a pain to calculate in Excel.  So, I hope this guide can make it a little bit easier to others.

One-Variable Chi-Square Test in Excel

I am teaching a new online class this semester, which means that I will be making more guides again!  today, I just made a guide on calculating one-variable chi-square tests in Excel.  Because the “Data Analysis” add-on in Excel does not have this function, they are a pain to calculate in Excel.  Nevertheless, I hope this guide is hekpful to some.
