Yielded Students: Preadmit Social Network
I recently finished the D3 social network graph that I started a couple months ago. The results are interesting, though messy. I didn’t do any advanced graph calculations so the following is all just based on visual inspection.
Some basic insights:
- Between the 67 nodes, we had over 750 edges
- 1 node = individual person, 1 edge = relationship between two nodes.
The most isolated nodes had 0 links/edges (i.e. didn’t know anybody at the university prior to attending)
- The most connected node had more than 30 links.
- These were students that attended the university’s summer camp program.
That’s an average of 11 edges per node (i.e. the mean number of connections per person was 11).
19% of the nodes aren’t connected to the main group (i.e. no nth degree connections to the largest group in the graph).
In general, the individuals who had the least connections, still have fewer connections. While this seems obvious, I feel like it’s still worth noting that it’s (generally) easier to add linkages than to break them, so those with more initial connections maintain their more-connected status.
By far the most connected group was the Tajik GBAO students. This is not surprising as the region seems to be more tight-knit, geographically concentrated and isolated, and religiously/ethnically homogenous than the other places.
Kyrgyz, non-GBAO Tajiks had average connectedness (due to larger geographic spread).
- Pakistani, Kazakh, and Afghan students had low connectedness (even larger geographic spread).
This graph is interesting because I highly doubt there are many other universities that have this level of interconnectedness prior to admissions. At Yale, I knew four people prior to attending and that seemed pretty normal; a lot of my classmates knew zero to two people? Of course there were people who went to more famous high schools and probably knew 30+ people but that wasn’t very common at all.
In conclusion, I hadn’t realized how generally connected the students were but it does seem to explain some of the interesting social dynamics, post hoc.
