Methodology
- Source: Pinellas County Property Appraiser parcel records loaded into the app database.
- Headline KPIs use exact database aggregates and ordered medians against the filtered queryset.
- EDA charts and segment tables use pandas/numpy transformations over the analysis frame.
- Outliers use IQR or top-metric rankings and link back to parcel drilldowns for auditability.
- No predictive model is used in this version because the public dataset lacks MLS sale prices and reliable beds/baths coverage.
