q2 · i? · associational · r?

Reporting methodology described in the Your School Productivity Profiles section: school profiles label all three trends for each year as up, down, or flat, and the guide states it "used statistical criteria to make these determinations" so the labels carry statistical significance.

"We have used statistical criteria to make these determinations so that "up" and "down" are statistically significant trends."

• Productivity profiles in adjacent grades are negatively related, so judging a school from selected grades alone can be very misleading — related
