If the range spans an order of magnitude, should I consider the logarithmic or linear midpoint? That is geometric or arithmetic mean between the ends?

- altdataseller 3y agoThe latter
- Spooky23 3y agoThey’re HR people - a log is a thing that used to be a tree.
- verelo 3y agoNo hate for HR but i have to share a funny line my previous business partner used to quote: "These people are often neither humane nor are they resourceful"
- cutemonster 3y agoAt least they provide resourceful humans :-)
- carlob 3y agoIs the midpoint between 20k and 80k 40k or 60k? Is the midpoint between 10k and 1M 100k or 505k? I think intuitively when the span is large we easily reason in logarithms even with little math training.
- pxx 3y agoBut the (geometric) midpoint between 100k and 1MM is $316,227 which might be surprising to some.
- mrits 3y agoEither works but using the logarithmic could be a lot harder finding the correct base
- cutemonster 3y agoAnd you'll make less money Or ask HR: What's the logarithmic mean base for your salary range?
