How are these prices computed?
The prices per m² shown are the medians of real sales recorded in the French DVF dataset, filtered to exclude atypical sales (multi-lot, new builds, outlier prices). The median is more robust than the mean: it is not pulled by extreme transactions. The p25–p75 range shows the most common price spread: half of all sales fall within it.
