Workout Wednesday: Visualising the National Student Survey with Spine Charts

Emma was back at it again with her sneaky tricks for Workout Wednesday week 24. Read the requirements here. I'd never built a spine chart before so this was a fun challenge and great learning experience. I did do a few things differently than Emma though:

1. My main viz with the table and spine chart is all one worksheet. Emma chose to split it into two.
2. My calculation for the % Agree is different than hers. She went with a straight average while I went with a weighted average. 
3. For one of the filters I used a data source filter while she used a context filter. Both work, just different approaches.
