And my point was that parchment is certainly NOT data.
They can perform all kinds off statistical testing, but the point is that they have no ‘sample’, as they perform no standardized sampling (as pollsters might do). As CU notes, anyone can setup an account to favor their chosen school/alma mater and ■■■■■ the main competitor. Parchment has no way to know the accounts are bogus.
Think about it: how many kids who can get accepted into Chicago (using your example) would waste their time going on to Parchment just post their cross admits. I know my kids just rolled thier eyes and said, ‘why’? My son added, ‘I have better things to do, like Fantasy Football.’
