In the study, HVAC companies with more Google reviews tended to reply to a larger share of them (rank correlation 0.38; association only).
Among HVAC companies in the study with at least 5 retrieved Google reviews, companies with more reviews tended to reply to a larger share of them (rank correlation 0.38); this is an association, and it is much weaker within review-volume groups.
Rank correlation 0.38 across all companies in the study with at least 5 reviews; within review-volume groups the association is much weaker (-0.17, 0.14, 0.19). An association only.
