Dataset Generator from Dr. Richard Landers

So. I shared my little blog on the Teaching of Psychology list serv last week. And within the next 24 hours, I received about 1000 page views, which blew my mind. Honestly, I know it can be an up-hill battle to teach statistics and I love the idea that maybe I'm giving my colleagues some new ideas to spice up their classes.

Better yet, I received emails from fellow psychologists with websites to share. One of these psychologists was Dr. Richard Landers from Old Dominion University.

So, is it just me, or has anyone else thought, "Gosh, I wish I could just create a data set for <insert statistical test here> that would be <sig/ns> so that I could ensure that my students had the experience of analyzing that kind of test?"

Well, Richard's website will provide you with exactly that! Not only do you get the data set, but you get the APA write up and output for the data as well! Richard created it as a study guide for his students but I can see where an instructor would benefit from it as well.

Additionally, here is a link to Richard's lab website

Thanks, Richard! Additionally, if anyone else has any ideas for good sites to share, please email me.

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.

Tyler Vigen's Spurious Correlations

Tyler Vigen has has created a long list of easy-to-paste-into-a-powerpoint graphs that illustrate that correlation does not equal causation. For instance, while per capita consumption of cheese and number of people who die by become tangled in their bed sheets may have a strong relationship (r = 0.947091), no one is saying that cheese consumption leads to bed sheet-related death. Although, you could pose The Third Variable question to your students for some of these relationships). Property of Tyler Vigens, http://i.imgur.com/OfQYQW8.png Vigen has also provided a menu of frequently used variables (deaths by tripping, sunlight by state) to help you look for specific examples. This portion is interactive, as you and your students can generate your own graphs. Below, I generated a graph of marriage rates in Pennsylvania and consumption of high fructose corn syrup.
