My students learned how to filter their data in the code.org lessons and some of them were cleaning only the class data that was filtered on 7 hours of sleep. I had to keep telling them to use the entire data set. I will admit that I thought this was easy enough for them to navigate on their own and took to grading while they were working on it. In the future I will very clearly emphasis the difference between filtering and cleaning.
