About this tour

How this score is calculated

This score is based on one provider. Viator rates it 5.00 from 20 reviews. We place that rating among all Viator ratings and weight it by its review count. If the tour is found on another provider later, both ratings are combined.

How the score works and rating distribution in Rome
  • Each provider rating is turned into a percentile: the share of that provider's ratings it beats, weighted by review counts.
  • Listings on different providers are combined in proportion to their review counts.
  • Tours with few reviews are pulled toward the average until more reviews come in, so a handful of perfect reviews can't top the list.
  • The result is shown from 0 to 10: this tour scores 8.0. Top 13% in Rome means it ranks in the top 13% of tours in Rome by this score.
