So I've tried everything to reproduce what in excel would be a simple average of - Average(S3:T3) to produce $5.79. How would I write this as a query in PowerBI to produce $5.79 as an average? They are essentially the exact same metrics from two separate tables.
Use following construct where you would need to replace Column1 and 2 by your column names in PQ.
= List.Average({[Column1],[Column2]})
