Today in AP Statistics class we improved how we graph a histogram and normal probability plot on the TI-Nspire CX calculators. We did both of these yesterday in the lab using R.
Yesterday, while using R within RStudio, I had the students export their code and plots using knitr and submit to me on our Moodle page.
But today, as we finished up section 2.2 in the TPS4e text book, I wanted to make sure my students could program the calculator to show a histogram and normal probability plot. They all helped each other as they explored the many menus and sub-menus. We also used the guide in the back of the book to help us through.
This is my first time using the TI-Nspire CX and the color monitor does a great job of displaying the graphs and plots. I’ll continue to use both R and the TI-Nspire CX to learn Statistics this year.
I’m glad I picked the TI-Nspire becaue the color monitor really brings the graphs and plots to life. Also, our plots in R are also in color so anything in black and white seems out dated.
My next challenge is to learn how to import a data set into the the TI so it doesn’t have to be typed in. Update on this next week.
