Can someone explain what is a 5 number summary in panel data? or What is a 5 number summary in panel

Thanks everyone! This totally clears up what is a 5 number summary in panel data for me.

I tried the `plm` package in R like someone suggested, and it’s way easier to see trends now.

Quick follow-up: How do you handle missing values when calculating these summaries? Like, if a panel unit has gaps?
