Deliverables: Kappas, percent agreement for above items, Overall.
VI. Scoring
1. Construct scoring system for how healthy a store is
2. Obtain frequencies and summary statistics for Scoring System overall
3. Obtain frequencies and summary statistics by Fast food/sit down indicator
4. Obtain frequencies and summary statistics by neighborhood
