Aggregations are functions which allow you to consolidate numerous rows of values into a single output. SUM, AVG, MIN, MAX, COUNT and COUNTD are some of the most used aggregations in Tableau.
Aggregations play an important role in Tableau calculations. If they aren't used properly, calculations will return incorrect results!
If you are writing formulas to calculate ratios, percentages or time period comparisons, it's very likely that you need to incorporate aggregations to return correct outputs.
