Hi all,

I am getting my students to remove data of their choosing from a table in a graph. This will change the regression line + statistics.

On the next slide I want to ask the question ‘The value of r of you regression line was ${r} … interpret what this means…’ As the data removed will change (student to student) I need to reference the r value from the previous graph somehow but can’t see any previous threads that suggest how this might work… Coding that works for other variables doesn’t seem to work:

r = g3.number(“r”)

Activity I am working on is here. Slides 5 and 7 are the relevant ones…

Many thanks,

Paul
