In task 3, the average number of products per order by city is calculated using the following formula, along with grouping by city: SUM(totals_transactions) / COUNT(DISTINCT fullVisitorId) However, this formula seems to only work in environments where a user can make only one purchase. Essentially, each distinct visitor ID must correspond to a single order. I'm not sure if this assumption holds, as there appear to be duplicate values in the visitor ID field.
