Online Day 6: One-way ANOVA example

I hope everyone is hanging in there.

Here is a pretty straight forward one-way ANOVA example that is interactive, based on for-real personality psychology research, and interesting. I blogged about this previously but whipped up a Google Slideshow you can download and edit to suit your own teaching. Also, I uploaded data that you can use with your students.

TL:DR-

A bunch of researchers gave the NEO to 1.5 million Americans to determine if different regions of the US have different personality trends (see research here).

Original Study

They do.

Then Time magazine reported on the study. And the scicomm was beautiful. They accurately described the research AND created a fun interactive portion in which you students can take the NEO-Short Form and be matched with the state that best matches their personality (Hi, I am West Virginia because I'm high in neuroticism and low in openness to new experiences, which are great qualities to have during a pandemic).

Good SciComm from Time Magazine

They shared their data. I turned it into a CSV and an XLSX for you. My version of their data includes a Region column, which divides the state data into four regions recognized by the US Census Bureau: South, West, Northeast, Mideast. So, this is a departure from the original research which found three regions through...not ANOVAs. But still, the data works as an ANOVA.

Ways to use funny meme scales in your stats classes

Have you ever heard of the theory that there are multiple people worldwide thinking about the same novel thing at the same time? It is the multiple discovery hypothesis of invention . Like, multiple great minds around the world were working on calculus at the same time. Well, I think a bunch of super-duper psychology professors were all thinking about scale memes and pedagogy at the same time. Clearly, this is just as impressive as calculus. Who were some of these great minds? 1) Dr. Molly Metz maintains a curated list of hilarious "How you doing?" scales. 2) Dr. Esther Lindenström posted about using these scales as student check-ins. 3) I was working on a blog post about using such scales to teach the basics of variables. So, I decided to create a post about three ways to use these scales in your stats classes: 1) Teaching the basics of variables. 2) Nominal vs. ordinal scales. 3) Daily check-in with your students. 1. Teach your students the basics...

Leo DiCaprio Romantic Age Gap Data: UPDATE

Does anyone else teach correlation and regression together at the end of the semester? Here is a treat for you: Updated data on Leonardo DiCaprio, his age, and his romantic partner's age when they started dating. A few years ago, there was a dust-up when a clever Redditor r/TrustLittleBrother realized that DiCaprio had never dated anyone over 25. I blogged about this when it happened. But the old data was from 2022. Inspired by this sleuthing, I created a wee data set, including up-to-date information on his current relationship with Vittoria Ceretti, so your students can suss out the patterns that exist in this data.

Logical Fallacy Ref Meme

So, I love me some good statsy memes. They make a brief, important point that sticks in the heads of students. I've recently learned of the Logical Fallacy Ref meme. Here are a couple that apply to stats class:
