Day 99: Applying Technical Writing

Today we begin confidence interval for means in earnest in AP statistics. Yesterday after the activity, the students explored what a t-distribution was via this Geogebra document and looked at how to determine a critical t* value from a table as well as from the Nspire. (sidenote: although we do find values using tables occasionally, I emphasize using their calculator to find these values as well as the area probabilities…its all about saving time on the AP exam, so training them now will help them to be comfortable using their calculator later during all of the inference procedures).

Today, we did our first write-up of a t-interval for means, emphasizing the conditions that need to be met.  I am so glad that I “over-emphasize” these when they are learning about sampling distributions.  Of course, we write one up together so they understand what needs to be shown and stated in the inference procedure.

As I’m writing this post, an idea popped into my head: a procedure wall!  Just like the word walls used in algebra and geometry classes but with the proper name of the procedure.  I’ll have a way to cover when they are taking an assessment.  I can use sentence strips, and maybe color-code for proportions vs. means vs. others.  Will have to ruminate on this a little more to flesh out the details…look for a future post on this!
