What's an outlier? I bet a lot of people feel they're shortchanged by about $10k, and will report that much higher to set a baseline. Outlier sounds more like "AngularJS developer making $250,000 in Cleveland"
it means more accurate baseline calculation as well as median salary which will rule out things like "AngularJS developer making $250,000 in Cleveland"
This is the first salary listing I've seen that actually looks somewhat accurate (at least for some titles) I am confused why you guys aren't using the title standardization. You're surfacing and getting different results for "Senior Software Development Engineer" and "Senior Software Engineer" (whatever those mean). You should talk to someone in SNA about this. I think Qi is the guy now.
Also you're having sampling bias that's effecting levels. There's no way the median salary for a staff engineer is higher than a senior staff's. Again talk to Qi.
Why didn't you buy industry standard employer wage reported surveys like any employer of size does? They are readily available and the cost would be a drop in a bucket for LNKD.
