- stats:find the mean -
**drwls**, Sunday, May 16, 2010 at 7:49amIf you want the mean salary, you can only get an approximate value since you only have histogram data (the number per salary interval). Assume that the number 16 applies to a salary at the midpioit of the first interval ($7500), etc.

The mean will be

(16*7500 + 15*12500 + 11*(17,500) + 15*22500 + 23*27,500)/(16+15+11+15+23) = $18,375
