Can someone please explain the "Model" that's presented on answer keys for each section? i.e., "This is a model of scaled LSAT scores vs probability of getting the question right."

Is it just showing that, for example, if the grey bar had 141 - 150 - 160 and the percentage for the correct AC was 85% then that means 85% of people who scored a 160 got that question correct or what?

Thanks
