Recently, many departures happen in kpop bands, so I attempted to make a simple data-driven observation to see who successfully “separated” from their former group.
By comparing monthly Google search interest between K-pop groups and their departing members, I calculated the correlation coefficient before and after the member’s departure.
| Group & Member | r_before | r_after | r_difference |
|---|---|---|---|
| NMIXX & Jini | 0.69 | -0.02 | 0.71 |
| SKZ & Woojin | 0.55 | -0.07 | 0.62 |
| Treasure & Yedam | 0.4 | -0.22 | 0.62 |
| iKON & B.I | 0.77 | 0.31 | 0.46 |
| ENHYPEN & Evan | 0.41 | 0.31 | 0.1 |
| NCT & Mark | 0.75 | 0.87 | -0.12 |
| I-DLE & Soojin | 0.28 | 0.56 | -0.28 |
Basically, a higher r means a stronger correlation, so they are more “connected.” Therefore, a larger r difference suggests the member becomes more “separated” from the group over time, for example, Jini and Woojin show this pattern.
One interesting result is Hanbin’s consistently high r value, which really reflects his strong connection with the group even after departure. (leader..!)
However, I’m a bit confused about Soojin. The data shows that after her departure, she is actually more correlated with I-DLE, but intuitively it feels like the opposite.
Anyways, this isn’t a very precise analysis, but I still find the pattern quite interesting. Solo-ing nowadays is really hard…
