Career Development Center salary statistics

I was looking through NCSU’s website recently, and found a page that listed salaries for graduates with various degrees, this one: http://careers.ncsu.edu/getting-experience/salaries/ It was listed under the “getting experience” section.

It seemed fairly standard, until I found another version of the same page under the “Access for employers” section, this one: http://careers.ncsu.edu/access-for-employers/salaries/

The salaries listed are vastly different than the ones on the other version, despite ostensibly being from the same pool of respondents. Does anyone have any idea why the numbers are so different? Which one is accurate?

(Note: I’m not using these salaries as a guide to choosing my major. I just found it very strange that there were two different statistics for them.)

Fixed - one was last year’s data
