Here are some responses to my question, "What is a suggestion that you have to make the activity better?":
"No suggestions it was very fun"
"Have a bigger variety of things to choose from"
"Give more suggestions on the type of graphs."
Below, you will find the results of a survey that students completed to show their interest in the activity and their understanding. They responded on a scale of 1 to 5, where 1 indicates the least and 5 indicates the most.
