So last night, I posted a bunch of miscellaneous thoughts, including my story of how I heard Nathan Sterner misusing the term “Venn diagram” and how that prompted me to donate to the pledge campaign. Well, somewhere in the middle of the night as I was attempting to rock Mark back to sleep (skin-to-skin didn’t work last night, sadly), I had this sudden thought, “Oh no! What if there’s an obscure variation of Venn that I don’t know about that actually works with his illustration? I’d feel terribly silly!”
So this morning, I went back to the Wikipedia entry that I linked to yesterday and read it more thoroughly and discovered two things.
- I’m right and Nathan’s wrong when it comes to Venns.
- What he was describing is also a graphic organizer! It’s called a Euler diagram.
So I drew up a couple diagrams to help us all understand the issue.
First, a Venn, properly used, to describe WYPR listeners and members:
Second, a Euler, to illustrate Nathan’s point:
All clear now? 🙂 Class dismissed!
Thank you! I’m a listener, not a member, and I wouldn’t have known a Venn diagram. I know what it is, right? Just not that it was called that. Now I know.
Glad I could help! I have to pull out my teacher hat every now and then!
And now the difference between a Venn diagram and a Euler diagram has been permanently etched into my mind! 🙂
Glad to be of help! And I hope you know this was done in the best, most positive spirit possible! 🙂
