Nothing freaks out your students faster than a formula, right? Karly over at The Novice Professor shares some worksheets she created for her students to step them through a few of the most common Intro Stats formulas: standard deviation, z-scores, and correlation.  http://www.thenoviceprofessor.com/blog/teaching-statistical-methods-mostly-formula-free Reasons to use in class: 1) Statistics has its own anxiety scale. I think a lot of that anxiety comes from the math part of a stats scale. These hand outs allow you to introduce the math and formulas without ever using the math and formulas. 2) I am a big fan of introducing statistics conceptually then getting into the nitty gritty of calculation, interpretation of output, etc. I like the formula-free approach here in order to introduce the idea of what frequently used stats, like SD, are really doing.

As a research-parent-nerd joke before Christmas, six doctors swallowed Lego heads and recorded how long it took for the Lego heads to pass. Why? As to inform parents about the lack of danger associated with your kid swallowing a tiny toy.  I encourage you to use it as a class example because it is short, it describes its research methodology very clearly, using a within-subject design, has a couple of means, standard deviations, and even a correlation. TL;DR: https://dontforgetthebubbles.com/dont-forget-the-lego/ In greater detail: Note the use of a within-subject design. They also operationalized their DV via the SHAT (Stool Hardness and Transit) scale. *Yeah. So here is the Bristol Stool Chart  mentioned in the above excerpt. Please don't click on the link if your are eating or have a sensitive stomach. Research outcomes, including mean and standard deviations: An example of a non-significant correlation, with the SHAT score on the y-...

Press Rogers is a very generous person who has created a number of documents that illustrate the thinking/math behind a variety of statistics. Here is his illustration for ANOVA, which includes one way, two way, repeated measured, and mixed. https://pressrogers.com/documents/anova-overview/ PS: I found out about this resource via the Society for the Teaching of Psychology FB group , which is active and filled with great advice about teaching statistics as well as other psychology topics. 

Crash course website produces brief, informative videos. They are a mix of animation and live action, and cover an array of topics, including statistics. This one is all about measures of central tendency: Here is the listing under their #statistics tag , which includes videos about correlation/causation, data visualization, and variability. And, you know what? This is just a super cool web site, full stop. Here are all of their psychology videos .

This website is associated with Agresti, Franklin, and Klinenberg's text Statistics, The Art and Science of Learning from Data ( @artofstat ), and there are dozens of great interactives to share with your statistics students. Similar and useful interactives exist elsewhere, but it is nice to have such a thorough, one-stop-shop of great visuals. Below, I have included screengrabs of two of their interactive tools. They also explain chi-square distributions, central limit theorem, exploratory data analysis, multivariate relationships, etc. This interactive about linear regression let's you put in your own dots in the scatter plot, and returns descriptive data and the regression line, https://istats.shinyapps.io/ExploreLinReg/.  Show the difference between two populations (of your own creation), https://istats.shinyapps.io/2sample_mean/

Robert Grant's website Draw My Data  provides you with a blank scatter plot graph. You add your dots, and the website generates M and SD for your X and Y, as well as r for the relationship between X and Y. It even generates a data set for download. My Twitter handle, @notawful, has an r of -.485. Via http://robertgrantstats.co.uk/drawmydata.html Great for illustrating a specific kind of relationship (positive, negative, etc.) to your students. Also allows for much goofiness, like Alberto Cairo, who plotted a T-rex and went viral. And then the T-rex plot, and a bunch of other plots, were used to create an animated, updated version of Anscombe's Quartet . And that was presented at a conference by Matejka & Fitzmaurice. https://www.autodeskresearch.com/publications/samestats So, lots of stats goodness here. You can let your students play with Draw Your Data or use that website to generate data sets for use in class. You can also use the dino data to illustr...

Holy smokes. How am I just learning about this amazing resource (thanks, Amy Hogan, for the lead) now? The folks over at Annenberg, famous for Zimbardo's Discovering Psychology series, also have an amazing video collection about statistics, called "Against All Odds" . Each video couches a statistical lesson in a story. 1) In addition to the videos , there are student and faculty guides to go along with every video/chapter. I think that using these guides, and instructor could go textbook free. 2) The topics listed approximate an Introduction to Statistics course. https://www.learner.org/courses/againstallodds/guides/faculty.html
