I think no. Most people don't do table joins very often. They wouldn't know how. What they'll do instead is create lookups with VLOOKUP or INDEX(MATCH()) to pull in values from other tables into their one master. And once they have the master flat file they'll use a pivot table for group by aggregations.

This is very accurate in my experience, down to the suggested formulas.
