Question

PLEASE HELP ME! “what examples or “clustering” can you think of outside of mathematics? “

Answer 1

I'm not sure exactly what it means in mathematics, other than putting similar things into groups.

So I guess you could answer with organizing similar things into group like the heights, favorite colors, ages, and grades of people in your class or something.

Is that what you're looking for?

Answer 2

Clustering is groups or hoards of things or people. Such as hoarders who cluster their houses full of items.
Or if your doing a collage of pictures on a poster board, your clustering the pictures together
