Short R script to plot effect sizes (Cohen's d) and shade overlapping area

I've been looking for applets that show this for YEARS, for demonstrations for classes. Thank you so much! Students do not need to tolarate my whiteboard scrawl now. I'm sure they'd appreciate you, too.l

Great webpage, I use it to illustrate several issues when I have a lecture in research methods. Thanks, it is really helpful for the students:)

Hard to overstate the importance of this work Kristoffer. Grateful for all you are doing.

Some really useful simulations, great teaching resources.

Thanks for fixing the bug yesterday!

This is awesome! Thank you for creating these. Definitely using for my students, and me! :-)

very useful for my students I guess

Preparing my Master's student for final oral exam and stumbled on your site. We are discussing in lab meeting today. Coffee for everyone.

What a great site

Wonderful work!

Terrific work. So very helpful. Thank you very much.

I am so grateful for your page and can't thank you enough!  

Wonderful work, I use it every semester and it really helps the students (and me) understand things better. Keep going strong.

Really super useful, especially for teaching. Thanks for this!

Very helpful to helping teach teachers about the effects of the Good Behavior Game

Amazing visualizations! Thank you!

So good!

Thanks for making this Interpreting Correlations: Interactive Visualizations site - it's definitely a great help for this psych student! 😃

brilliant simulations that can be effectively used in training

Amazing illustrations, there is not enough coffee in the world for enthusiasts like you! Thanks!

🌟What a great contribution - thanks Kristoffer!

Wow - your website is fantastic, thank you for making it.

Thank you Kristoffer This is a nice site, which I have been used for a while. Best Prof. Mikhail Saltychev (Turku University, Finland)

Keep up the nice work, thank you!

Thanks - this will help me to teach tomorrow!

Keep the visualizations coming!

Thank you so much for your work, Kristoffer. I use your visualizations to explain concepts to my tutoring students and they are a huge help.

Thank you for making such useful and pretty tools. It not only helped me understand more about power, effect size, etc, but also made my quanti-method class more engaging and interesting. Thank you and wish you a great 2021!

We've mentioned your work a few times on our podcast and we recently sent a poster to a listener as prize so we wanted to buy you a few coffees. Thanks for the great work that you do!Dan Quintana and James Heathers - Co-hosts of Everything Hertz 

Used your vizualization in class today. Thanks!

My students love these visualizations and so do I! Thanks for helping me make stats more intuitive.

For a high school teacher of psychology, I would be lost without your visualizations. The ability to interact and manipulate allows students to get it in a very sticky manner. Thank you!!!

You Cohen's d post really helped me explaining the interpretation to people who don't know stats! Thank you!

You doing useful work !! thanks !!

Enjoy.

Teaching stats to civil engineer undergrads (first time teaching for me, first time for most of them too) and grasping for some good explanations of hypothesis testing, power, and CI's. Love these interactive graphics!

Thank you for using your stats and programming gifts in such a useful, generous manner. -Jess

A job that must have cost far more coffees than we can afford you ;-). Thank you.

Thank you! Such a great resource for teaching these concepts, especially CI, Power, correlation.

Fantastic work with the visualizations!

Your work is amazing! I use your visualizations often in my teaching. Thank you. 

Excellent!  Well done!  SOOOO Useful!😊 🐭 

this is a superb, intuitive teaching tool!

Thank you so much for these amazing visualizations. They're a great teaching tool and the allow me to show students things that it would take me weeks or months to program myself.

Thank you for sharing your visualization skills with the rest of us! I use them frequently when teaching intro stats. 

Thanks a lot!

Thanks mate

Thank you, this really helps as I am a stats idiot :)

Really appreciate your good work!

Your visualizations really help me understand the math.

Thanks for making the poster designs OA, I just hung two in my office and they look great!

Thanks for your work.

Great work!

Thank you for building such excellent ways to convey difficult topics to students!

Really wonderful visuals, and such a fantastic and effective teaching tool. So many thanks!

I really like your work.

You're awesome. I have students in my intro stats class say, "I get it now," after using your tool. Thanks for making my job easier.

Incredibly useful tool!

Thanks for the assistance for RSCH 8210.

Great tools! Thank you very much!

Hi Kristoffer, many thanks for making all this great stuff available to the community!

These visualizations are awesome! thank you for creating it

Very nice.

Thank you for the visualizations. They are fun and informative.

Really helpful visualisations, thanks!

This is amazing stuff. Very slick. 

Thanks so much for creating this! Really helpful for being able to explain effect size to a clinician I'm doing an analysis for. 

Thank you! This page is super useful. I'll spread the word. 

Thank you so much for creating these tools! As we face the challenge of teaching statistical concepts online, this is an invaluable resource.

Fantastic resource. I think you would be well served to have one page indexing all your visualizations, that would make it more accessible for sharing as a common resource.

Fantastic Visualizations! Amazing way to to demonstrate how n/power/beta/alpha/effect size are all interrelated - especially for visual learners! Thank you for creating this?

Incredible visualizations and the best power analysis software on R.

Great website!

Thank you for this work!!

Nice explanation and visual guide of Cohen's d

thank you

This site is superb!

thank you for sharing your work. 

Thank you for the website, made me smile AND smarter :O enjoy your coffee! :)

Struggling with statistics and your interactive diagram made me smile to see that someone cares enough about us strugglers to make a visual to help us out!😍 

Much thanks! Visualizations are key to my learning style!
