My business statistics class started at Yokohama National Univerisy for the international students from all over the world.
Just to explain some basics for the new students, I was struggling to show the level of aggregation of data in my class.
This is a concept that you need to learn for managing data itself before studying some statsitics.
Today I found the word “granularity”.
I guess it is not that common word even for English speakers but it really fits the concept.
