Day 81: Movie Compatibility

Algebra is working towards linear regressions and today they started on scatter plots. A colleague reminded me of an awesome activity introducing scatter plots from MathyCathy’s blog that I had seen floating around twitter a couple months back. I jumped on the opportunity to go through it today.

My students were pretty solid on scatter plots so this was more of a fun review. They all enjoyed it and were able to interpret the graphs really well without much prompting on my end. Here are a few of the graphs

I used appleTV to throw these up on the board and discuss with students. Then we went into a few notes on the different types of correlations.

Great day!
