Yesterday I posted a rather sophisticated exploration of data from Ish Zamora on CoVid19, where using a logistics model and exponential growth, you could collect data and make predictions. This got me in a statistical mood, so I thought I would focus this week on statistics. We did a brief exploration of measures of center in a previous mini-lesson post, so this week will just expand on this, starting from a more basic look at different statistical plots, and then moving into some more statistical analysis by the end of the week, with regressions, and normal distributions, etc. In large part because Casio is offering the for-fee apps of CAS and AP Statistics free for the rest of the school year, so I want to make sure everyone is aware of the statistical options that are available on ClassPad.net. Check out other supports Casio is offering here, at Casio Cares (free hand-held emulator software, free ready-to-use ES-Calculus math lessons, etc.)

Today the focus is more at an elementary/middle school level, where we will explore measures of center and look at different plots and help students learn to make decisions about representations and descriptions. A continuation of what we did in the previous post. There are lots of opportunities in these activities for students to collect their own data (so be creative), though they can use the preset data if they want.

- ES – Statistical Measures and Graphs – What’s the Best Representation
- ES – Measures of Center w/Presidential Data
- ES – Dot Plots & Histograms
- ES – Box Plots & Histograms

The tool being used in these mini-math lessons is the FREE web-based math software, ClassPad.net.
