Everyone writes their salary on a piece of paper and puts it into a hat. Then you can get a the full distribution.
- jhanschoo 6y agoIf the salaries are still too easily identifiable here's how it can be anonymized. Allow breaking down the salary into a sum of numbers, and putting them as separate slips into the hat.
- verma7 6y agoHow would you get the distribution from the sum of numbers individually?
- jessaustin 6y agoYou don't count the slips of paper in the hat. Instead you count the number of people who put in slips of paper.
- nitrogen 6y agoThat will give an average, but it won't give the distribution (min/max/etc)
- chrisdirkis 6y agoI believe the parent meant breaking it down as "if you earn $100k, add 10 slips that each have $10k on them". The number of slips will be more than the number of people in the room, but that's fine. It's less practical than the "seed + pass round" method that someone else recommended imo (due to handwriting notability), but still works in a more technical sense.
- jhanschoo 6y agoYou're right, you can't, I was looking at the problem posed by grandparent comment of getting only the average.
- cheerlessbog 6y agoIf you know who is senior, who is junior etc you can identify their values
- cheerlessbog 6y agoOr use modified randomized response technique [1] Roll a die and multiply (salary - 100k) by the spots on the die. Share that value publicly. Sum all such values and average them then divide by 21/6 and add 100k. Choose the 100k value to be closest to but not greater then your guess at the lowest salary.
