Useful R Intro for new beginners here

I recommend R For Data Science

I also really like Statistical Rethinking by Richard McElreath.  Here is an amazing guide to the book with code written using ggplot2 and brms

PSYC 607 (Inferential Statistics and Experimental Design)

For Fall 2018 I redid the lecture on Descriptive Statistics to include hands on practice using R’s ggplot2 package to plot different types of data.  Students brought their laptops and did the R exercises during the lecture.  Many students had no prior programming experience.  The materials for this lecture are available on the osf by clicking here


Bayesian Statistics

I have taught Inferential Statistics and Regression at the graduate level since 2012.  These are the two courses graduate students in the Psychology department at Texas A&M University are required to take their first year.

Recently I spent a large amount of time learning about Bayesian inference and Bayesian data analysis.  This approach makes much more sense to me, and I gave a short course to graduate students and faculty at Texas A&M in May 2017.  The course was based on John Kruschke’s (excellent) book Doing Bayesian Data Analysis: A Tutorial with R, JAGS, and Stan. The book’s website is here.

I also recommend JASP.  It can basically replace SPSS to perform traditional analyses and it also easily performs Bayesian analyses from the General Linear Model, yielding Bayes Factors that can replace p values.

The course covers Bayesian Inference and includes hands on lectures that cover both the model comparison approach that utilizes Bayes Factors, and the parameter estimation approach that focuses on 95% highest density (or credible) intervals.  I favor reporting Bayes Factors instead of p values and 95% HDIs for parameters instead of confidence intervals.

I have provided the power points for the course lectures to facilitate the field’s switch to Bayesian approaches.  I highly recommend purchasing Kruschke’s book as well.   The JASP tutorial is based on a tutorial E.J. Wagenmakers and others have written and made available on the Open Science Framework here.
