Choosing Median vs Average for metrics

Choosing Median vs Average for metrics

Some stats programs give the user the choice between using Median or Average aggregations for metrics.  Domus typically does not offer that choice, and the reason is simple.  The decision to choose between Median and Average for any aggregation is mathematically determined by the distribution curve of the data.  In other words, it isn't a "choice" the end user should be tasked with making.  In some situations, Median is more accurate.  In others, Average is preferred.  And in some situations, they both converge to the same result, so having a choice is redundant.  Making the user of a dashboard choose which aggregation to use may seem like a "feature" on the surface, but it leads to unnecessary complexity, and can result in the agent conveying inaccurate economics to their clients.  So rather than putting that burden on the user, we just give you the correct answer.
