Sets: Sets are subset of data created according to specific conditions or criteria.
Once created, we can use the sets in analysis. A set can have data based on a condition like sales values greater than 50,000.
Groups: Groups in Tableau refer to the group of dimensions brought together to create a category.
For instance, if we are analyzing test scores for different majors, we can create a group called Major that will contain all the majors for a test.
