Robert Grant's website
Draw My Data provides you with a blank scatter plot graph. You add your dots, and the website generates M and SD for your X and Y, as well as
r for the relationship between X and Y. It even generates a data set for download.

Great for illustrating a specific kind of relationship (positive, negative, etc.) to your students. Also allows for much goofiness, like Alberto Cairo, who plotted a T-rex and went viral.
And then the T-rex plot, and a bunch of other plots, were used to create an animated, updated version of
Anscombe's Quartet.
And that was presented at a conference by Matejka & Fitzmaurice.

So, lots of stats goodness here. You can let your students play with Draw Your Data or use that website to generate data sets for use in class. You can also use the dino data to illustrate why it is important to graph out data.
