Day 13 (09/18/14)

Blogging from an iPhone watching a soccer match.

AP Stats: First test tomorrow. Kids took a practice test and we discussed the answers today. Good luck, guys.

Stats & Data: We had some fun calculating standard deviation by hand. Just one. Then we looked at different graphical displays to determine which had the largest standard deviation. We didn’t have time for the geogebra activities today. Sounds like a good warm-up tomorrow.
