How do you raise above average?

For many of my reports I start with AVERAGE and then improve the metrics to show insights. I try weighted average, median, mode, visualizations and conditional averages.

What about you? What analytical techniques & formulas do you use apart from AVERAGE()? Please share your thoughts using comments.

    Just add a column calculating the "performance" or whatever is your criteria and sort by it? No?
    have no patience to waste 13min. Save your time too.

  2. Andrew says:

    Just thought I would mention, the "weird" custom sort behavior mentioned at 5:45 where "% return" doesn't appear to be sorting is because the "August Purchases" field has the sort preference and since these are such unique values, no additional sorting is possible on the "% return" field. If there were two entries that had the same "Customer Since" year AND the same "August Purchases" amount, THEN you would see a sorting of the "% return" on these two entries.
