I have a bunch of statistical data and I want to present a short summary to the user (non-technical consumer). Now I want to show an average and need to decide between arithmetic mean and median. From a mathematical point of view, the median would be better due to the possibility of outliers skewing the average.
But I'm unsure if users understand the word and concept median. I suspect, many users don't know the difference between the two and think of the mean when they hear average.
So, should I use the mean (possibly more easy to understand) or the median (possibly better for interpretation)? Or maybe I could use the median but call it average? But that might confuse or deceive people, or not?
