Mediation and Moderation in Jamovi

Hi all! I just added two new pages to MattCHoward.com for conducting statistics in Jamovi. The first covers mediation in Jamovi, whereas the second covers moderation in Jamovi. Links are below, and, as always, feel free to reach out if you have any questions. My email is MHoward@SouthAlabama.edu.

Several New Help Pages on Jamovi

Hi everyone!  I spent all weekend making several new help pages on the statistical software, Jamovi.  It is a wonderful and free program that can perform most basic statistical analyses, and it functions similarly to SPSS.  Because my students cannot use the on-campus computer lab at the same time this semester, I am instead teaching my stats courses using Excel and Jamovi.  It is quite the lifesaver!

Below are links to the new help pages that I made.  Also, here is a link to my page with all Jamovi guides: https://mattchoward.com/jamovi-statistics-help/ .

Please let me know if you have any questions, comments, or requests regarding Jamovi.  I am always happy to talk about such a wonderful program.  Thanks!

I just finished uploading my latest lecture to YouTube.  It covers how to perform one-sample t-tests and two-sample t-tests in Excel.  While both are extremely important statistics, the latter cannot be easily calculated in Excel.  So, I hope that this video is helpful in figuring out how to calculate the statistic.

One-Sample T-Test in Excel

Although I’ve been putting it off for months (years?), I finally made a guide on performing a one-sample t-test in Excel.  The “Data Analysis” add-on in Excel is not able to calculate this statistic directly, so we have to trick Excel into calculating it for us.  Nevertheless, the guide provides clear instructions on how to do so.

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 halfway 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 a 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 helpful to some.
