Exercise

Masterclass: Tidy III

In the previous exercise, you visualized the size of the "finale bump" in viewers for each series. From those charts, we know that finale episodes always garner more viewers than premieres. We also know that the change in viewers for series 8 seemed smaller compared to some previous series.

But the question of whether the series 8 finale viewers were "spoiled" might be best answered by comparing the relative percentage changes in premiere and finale viewers across series. In this exercise, you'll reshape first_last once more to calculate and visualize the relative finale bump.
