Spurious correlations, three ways

I stumbled across a collection of spurious correlations a while back.

Here is one of them that struck me, in part because the data set links sour cream consumption per capita and motorcycle riders killed in non-collision transport accidents, but also because it is presented in odd sort of way.

Headline: Sour cream consumption linked to greater risk of non-collision transport death by motorcycle.

SBG Targets: Rubric or Checklist?

As I prepare learning targets for my next unit of instruction, I am contemplating whether it might be useful to split my targets into two categories: Checklist Targets and Rubric Targets.  

Crowd-sourcing Our Midterm Review

I had to take a sick day today, so we are reviewing for our Mth323 midterm exam by crowd-sourcing a review guide. Students have been asked to add at least two tips for our learning targets, plus as many questions as they have. Check it out (updated every 5 minutes or so):

A Question of Balance

This post is based on a student comment that caught my eye while grading. The data below shows the sodium content (in mg) for 23 brands of "regular" Peanut Butter.

The student wrote one of the following two statements in defense of choosing the preferred measure of center.

1) The data are balanced on each side of the median.
2) The data are balanced on each side of the mean.

Which statement do you think is more correct? In what sense might someone think the other one is correct, too?

Ready... GO!!
