New college admissions tool: Interactive flash scatterplots

We have rolled out our interactive flash scatterplots (also known as scattergrams), available on every college page under the ‘My Analysis’ tab.

These graphs display the accepted and rejected applicants scattered across a 2D canvas according to the variables that you choose. For example, you might look at Unweighted GPA & SAT, or Instate & Average AP Score. To get started with this new tool, see Cornell’s scatterplots.

For any given SAT score, valedictorians appear more likely to get into Cornell than non-valedictorians.

For any given SAT score, valedictorians appear more likely to get into Cornell than non-valedictorians.

Because there are many, many overlaps, you can set a level of jitter, so each point floats near its true value. For example, if you look at Unweighted GPA and Valedictorian Status, everyone will clump on top of one another. (You either are a valedictorian, or you aren’t, so there are only 2 slots that you might possibly fit into – hence lots of clumping.) If you set a 20% jitter to Valedictorian Status, things will spread out nicely, so you can see what is really going on.

With your feedback and criticism (please post it here or in the forums), we’ll work on improving the tool. Enjoy!

These display the accepted and rejected applicants on the same canvas. You can choose which dimensions they’ll be displayed against (unweighted GPA and SAT, for example).

Clickable scatterplots

We’ve had scatterplots for some time now. Scatterplots, I think, are good for showing how scores cluster. In general, you’ll expect to see acceptances at the top right (highest GPA and highest SAT), with rejections beneath that and to the left. If you break down law school statistics, they tend to go by the numbers. However, if you look at some of the top schools for undergrad, it becomes clear that it’s not just a numbers game.

For example, you might see the UC Berkeley scatterplot and think, ‘How did that guy with the 4.0 2400 get rejected?’ Well, instead of searching the list of UC Berkeley applicants, you can just click on the dot to read his story, because each dot on the scatterplots now links to the user’s profile.
