Ah, the article is actually extremely unclear. What I took his conclusion to mean was that some cohort of gyms that had signed up post-change had lower cancellation rates than pre-change customers. If the analysis just took into account the overall rate across all customers is prone to all sorts of errors (including the one you mention).
- ehsanu1 14y agoMy impression was that the pre-change cancellation rate was based on all customers over the lifetime of the product (they did calculate the 61 day average from this), whereas the post-change was only for the new customers in the last two months (the max it could be, and the only thing it makes sense to measure).
