@Bruno I would recommend modifying the Instructions for this part of the Guided Project.
The instructions ask us to explore certain relationships using scatter plots. And then pose us questions stating -
Use **the plots** to explore the following questions
the plots makes it seem that we are supposed to look at the plots we already created.
But two of the questions don’t correspond to variable/features being plotted. And it becomes slightly confusing as to whether or not we (students) can answer those questions with just those plots. Creating new plots to answer those questions might seem obvious to some students, but not all.
My general recommendations to help everyone learn through this better would be -
Either add those features in the instructions for creating the scatter plots so that the questions can be answered.
Or, create two separate set of questions. One set is relevant for the already created scatter plots. One set asks students to create plots to answer questions by identifying the necessary features themselves.
Or, instead of first asking to create specific plots and then answering questions. Just post the questions, mention what features can help answer those questions and ask students to use scatter plots to answer those.
The 2nd one is the best option as per me.
There are other improvements I could maybe suggest, but don’t wish to trouble you
