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/ .

Chi-Square in Jamovi

Cronbach’s Alpha in Jamovi

One-Sample T-Test in Jamovi

One-Way ANOVA in Jamovi

Two-Sample T-Test in Jamovi

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!
