What's the Best Way to Go About Normalizing Data for Better Analysis? or How Important Is Normalizing

Wow, thanks everyone! Didn’t expect so many replies.

I tried sklearn’s StandardScaler like a few of you suggested, and it’s way easier than I thought. Still tweaking things, but it’s already cleaner.

Quick Q: what do you do when some columns are binary (0/1)? Normalize those too, or leave ‘em?

Also, that cheat sheet link was gold—thanks for sharing!
