My talk last night at the visualization meetup

(This article was originally published at Statistical Modeling, Causal Inference, and Social Science, and syndicated at StatsBlogs.)

It went pretty well, especially considering it was an entirely new talk (even though, paradoxically, all the images were old), and even though I had a tough act to follow: I came on immediately after an excellent short presentation by Jed Dougherty on some cool information and visualization software that he and his colleagues are building for social workers.

The only problems with my were:

(a) I planned to elicit more audience involvement but didn’t do it. It would’ve been easy: at any point I could’ve just paused and had the audience members work in pairs to come up with suggested improvements to any of my graphs. But I forgot to do it.

(b) I went on too long. The talk was going so well, I didn’t stop. In retrospect, it would’ve been better to stop earlier. Better for people to leave the table hungry than stuffed.

Also, next time I’ll drop the bit about the nuns-in-prison movies. People weren’t getting the connection to the point I was making about presetting the signs of variables before presenting an analysis.

And one new thing I tried: I know the slides will be read online, so I kept captions for many of the figures so you online readers can get more out of it, also I added a couple slides (pages 10 and 60) just for you, to clarify some of the points you otherwise wouldn’t get just by seeing the images.

Again, here are the slides.
