My stats students had just finished up learning to find IQR by hand and by calculator and standard deviation by hand (I know - I'm evil!) and by calculator. It was now time to discuss when each is more appropriate to report. I quickly decided to make a card sort for my students to complete.
I don't think I can post the file since the images are taken from Stats Modeling the World.
And, if I'm honest, I'm not entirely sure I have them sorted perfectly. Teaching stats definitely puts me outside my comfort zone. Anything that's not algebra is outside of my comfort zone. This is my fourth year teaching algebra 5 out of 6 periods a day. Algebra and I are good friends. Stats is just a visitor that stops in for an hour a day every other year. We've still got a long way to go to become well acquainted!
It was awesome to eavesdrop on my students' conversations as they worked to sort these graphs. I have a special place in my heart for card sorts. <3
