Ok, for ease of comparison, I've tabulated the data from this thread by discipline.
Some notes: To prevent skewing I threw out four outliers (of 60 data points) which were approximately four or more standard deviations from the average of their discipline, namely civilsurvey ($120k), BigRay76 ($115k), Benbo's semiconductor job ($128k), and Oilfield Engineer ($115k). If a person listed a salary range, I used the average of the range. If a variable bonus was listed, I used the average of the range. I used the field the person is working if their degree was in a different field. I put the Structural people in with Civil since I think there were only two Structurals. I did not try to account for length of experience or work location.
There were 26 Civil data points, 2 Chem data points, 6 Enviro data points, 11 Mechanical data points, 13 Electrical data points, and 2 Geo data points.
Results (rounded to the nearest $1k):
Overall Average = $67000 (note, the high number of Civil data points may have skewed this average)
Overall ST Dev = $15000
Civil Average = $61000 ST Dev = $13000
Enviro Average = $64000 ST Dev = $13000
Mechanical Average = $66000 ST Dev = $12000
EE Average = $79000 ST Dev = $10000
Sorry, there was not enough data for Chem or Geo to do any meaningful analysis.
I also broke down the data in other ways depending on how much data was available:
Civil, Bachelor's Average = $58000 ST Dev = $12000
Civil, Master's Average = $65000 ST Dev = $13000
Civil, EIT Average = $55000 ST Dev = $8000
Civil, PE Average = $67000 ST Dev = $13000
Civil, Bachelor's & EIT Average = $53000 ST Dev = $8000
Civil, Master's & EIT Average = $58000 ST Dev = $5000
Civil, Bachelor's & PE Average = $65000 ST Dev = $12000
Civil, Master's & PE Average = $70000 ST Dev = $13000
Enviro: Not enough data
Mechanical, EIT Average = $68000, ST Dev = $13000
Mechanical, PE Average = $61000, ST Dev = $10000
Electrical, EIT Average = $80000, ST Dev = $8000
Electrical, PE Average = $78000, ST Dev = $11000
For the most part, these results don't suprise me except for the ME EIT vs. PE. My only explanation for the lower PE values is I only had four data points for that set.
