Final answer:
The correct technique to exclude rows with fewer than 10 visits from a report table is to apply a table filter, which will remove rows that do not meet the specific visitation criteria.
Step-by-step explanation:
To exclude rows with fewer than 10 visits from a report table, you would apply a table filter. This option allows you to set a specific condition such as 'visits must be greater than or equal to 10', effectively removing any rows that do not meet this criterion. Options such as adding a primary or secondary dimension, sorting the table, and using a pivot table with two dimensions do not directly allow for the exclusion of rows based on the number of visits.
