[quote=Anonymous][quote=Anonymous]Anyone using Parchment to understand school comparisons doesn’t understand data and/or Parchment’s process. Of course, Parchment wants you to believe that their data reflects reality, but there is little reason to believe them.

Parchment’s data is 100% self-reported with absolutely no verification of reality. That means that it’s potentially rife with problems.

First, there is selection bias - who would/would not visit such a site to provide there data. It is not a complete or representative dataset.

Second, there is false data - people report comparisons and outcomes that are fake to put their thumb in the scale.

Third, there is no safeguard against one person or a group of people creating multiple accounts and “astroturfing” the results - essentially a coordinated effort to hype or degrade a school (much like DCUM trolls!).

What to trust? School data. Common App data. Given Vanderbilt’s admission stats and class profile, it’s very hard to believe the Parchment results. [/quote]
Parchment is not self reported, its using transcript data through counselors. Vanderbilt gets a ton  of applicants from students who have no chance at going. Especially southern students, so yea its believable. [/quote]
