Depends upon the size of the populations. This equation is used in larger pops and is the one used on the AP equations sheet. Khan Academy explains it in their population ecology lesson.
Have you ever read ecology? Simpson's index is useful for calculating diversity of species in a particular ecosystem based on which environmentalists analyze (richness, evenness and dominance of species) and plan strategically. Apart from this there's also Shannon's index, Hill numbers and certain other indexes which are all resourceful in some way. Please do proper research before commenting. Khan academy is for all sciences, not just pure math and stats, CS, engineering and physics.

I wouldn’t be passing without this man😂
I think what you describe is the Gini-Simpson index, because it subtracts the simpson index from 1 (to make it easier understandable).
And here I thought Bart Simpson was a slacker.
Great explanation.
LOVE U KHAN
SAME 🥺
thank you!
what is the difference between Simpson's diversity index and Simpson's index of diversity
Woah.
right
Wow... is this a dream being 3 to comment on a khan academy vid?!
Thank you thanks soo much dear teacher 👑💯
Nice
Your other video on this topic used a different formula, why?

Sal is the best
I think I'm the only one who came here because someone mentioned that this guy sounds like Mr. Nightmare 😄😄

OMG HE USES A MACBOOK
I hate that the voice actor for Apu quit but, strange times.

If you're going to truncate, the correct approximation would be 0.665, not 0.664
Mate nobody cares upload more real maths, computer science, physics and engineering
they are trying there best :( 🥺
This is math. It's just a formula that's used predominantly in Biology.

Triggered by the word diversity lmfao
Bruh, this is a part of AP Bio. Its hella useful
