Hi @jasperlafortune! This is one of those "thinking prompts" where there is no one right answer. The Teaching Tip in the lesson provides some guidance. Here's what it says:
"Please note: this data is completely fabricated and is only intended to serve the purposes of the warm up. It is intentionally slightly ambiguous. If students ask questions seeking clarification that's a good sign, but you might have to simply respond: "Well, this is the data we have".
There are no right or wrong answers here as long as students attempt to represent the data in a different way somehow."
I would hope my students would say that this isn't great data to start with. If anything, I would think it is interesting about who they were able to ask or how they decided to break down the age groups in the way they did. I would also think we could talk about how "talking with friends" was the most popular for all ages, but not for any single age - that might mean that it was a close second in several of the categories.
Again, I read this as a "get students talking and thinking about data" type of question - not necessarily a formative assessment on how well can students select a way to represent data in a story. I think this foreshadows the lesson for the day and perhaps increases student critical thinking skills on data and connects it back to the "bad data visualizations" lesson. I could see someone taking this data and doing all sorts of terrible things with it... hopefully this data gives students some empathy for people making data visualizations with less than ideal data.
I'm curious what your students come up with though!
