Baby Name Distributions
http://fivethirtyeight.com/features/how-to-tell-someones-age-when-all-you-know-is-her-name/
I am fascinated by baby name trends, but I don't know if students are. What I am most interested in with this is the intuition students will have about names, and how that helps set them up to understand distributions, especially bimodal distributions. I know that I have fairly set ideas about what names come from what eras (I hear "Agnes" and I picture an elderly woman; I hear "Kaylee" and I picture a young girl), so it helps with thinking about when median may or may not be the best measure of center. Also, there's a nice graph with interquartile ranges, which demonstrates why we care about the interquartile range. Finally, there's so much baby name data out there that kids could definitely research and construct their own graphs based on the questions that (I expect) will come up from looking at all this.

Graphing Stories: the Next Level
https://teacher.desmos.com/carnival/walkthrough#cannonman
This is so cool! It's like graphing stories, but the interactivity really helps hone in on kids' misconceptions around graphing. All those things about graphs just being pictures, about understanding what makes a function (beyond the vertical line test...), etc. are captured in the well-chosen scenarios.
I talk a lot of smack about blended learning or personalized learning or whatever they're calling it these days, but I am in no way opposed to technology use in the classroom. The Function Carnival is a great example of technology usage because it provides something that pencil and paper can't. Sure, it's probably engaging to a kid because it's on the computer and it has fun animation, but technology purely for engagement's sake is not enough. This technology also doesn't just feel like a way for teachers to measure some percentage of material learned. Those things are fine, but not really enough (at least for me). But this tool helps kids deepen their understanding of function from very different perspective. That is what technology should do--it should enhance teaching, not replace it.

Who's Lurking behind These?
42 strange things that correlate:
http://tylervigen.com/
Obviously, it's interesting fuel for the "correlation is not causation" discussion, particularly because it's interesting to think about what the lurking or confounding variables might be.
What I also think is interesting about these graphs is some of the graphs that seem to follow each other closely, but don't really have that high of a correlation coefficient. For example, Number people who drowned by falling into a swimming-pool vs. Number of films Niclas Cage appeared in. Most of the data has an r above .9, which is good, but I think it would be interesting for kids to talk about why the curves on that graph seem to rise and fall together, but the correlation coefficient is not really that convincing of there being a statistical correlation.
Also cool: if you click on one of the variables, you can see how it correlates with a whole mess of other variables. This site could clearly could be a huge time suck for stats teacher trying to find interesting data to work from.

Mario's a Baller
http://www.supercompressor.com/tech/13-things-you-probably-didn-t-know-about-nintendo
See fact #9: Mario has a 27’ vertical leap.
See fact #9: Mario has a 27’ vertical leap.
This seems like a fun addition to "How High Can Your Teacher Jump?" or any kind of proportional reasoning kind of thing.
What would we look like if we measured human heights in pixels? What would that mean for how tall Mario is compared to a human? How much bigger is Big Mario vs. Little (pre-mushroom) Mario? How big would YOU be if you ate a mushroom (or alternatively, if you're full size now, how tall would you be after running into a goomba)?
Do kids even recognize pixelated Mario anymore these days?

Graphing Stories
I love having kids play with the story that a graph tells, or creating a graph that describes a story. I like this take on it: video.
http://graphingstories.com/
I'm not sure I agree with all their categorizations, but that's fine. I like that there are a decent amount of video clips where the graph will not end up just looking like a picture of what happened (e.g. time vs. altitude when someone is climbing a mountain doesn't really help kids make sense of axes).
Just as important as having this library, it makes me think about other quick, easy activities that you could film and have kids graph. Extra bonus: have kids make their own 15-second films or find YouTube clips of something you could graph.

Poor Pete Tries Data Visualization
http://wtfviz.net/
The title may not be school-appropriate, but the awful data representations are a goldmine of "What's wrong with this?" problems.

What is Wrong with these Charts?

Good lord.
Another interesting question: what is right with these charts? Poor Pete always does something right.

There's No Pleasing Everybody at Once

Questions to ask:
Why does it go down then up?
Could you put these all on the same graph?
