Sometimes being a research assistant has unexpected perks, like getting to read through the methodological notes of the IPEDS Data Feedback Report and finding this gem:

“In order to preserve individuals’ confidentiality, data in the Graduation Rates, Student Financial Aid, and Human Resources components of IPEDS are perturbed. Only perturbed data are available in the Peer Analysis System and the ExPT; the perturbed data were used in creating this report.”

Are you picturing the face of perturbed data? I am.
