Simpson's index of diversity | Ecology | AP Biology | Khan Academy

Keep going! Check out the next lesson and practice what you’re learning:

Species number and relative abundance affect the diversity of a community. We can use Simpson's index of diversity to quantify and compare the diversity of different communities.

I wouldn’t be passing without this man😂

[@mytube8106]

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.

[@DailyDoseDocumentary]

Great explanation.

LOVE U KHAN

SAME 🥺

[@vijayishak7139]

what is the difference between Simpson's diversity index and Simpson's index of diversity

[@masaltzero]

Woah.

[@cynthiavaladez9687]

right

[@amnashaikh-sl1qi]

thank you!

[@hannahxeditz7439]

Wow... is this a dream being 3 to comment on a khan academy vid?!

[@wafaguzelik827]

Thank you thanks soo much dear teacher 👑💯

[@mikethegamedev]

Nice

[@paulinski011]

Your other video on this topic used a different formula, why?

[@sonnetmoore2732]

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.

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

[@ivandios4]

Mate nobody cares upload more real maths, computer science, physics and engineering

[@aurora-cc6hk]

they are trying there best :( 🥺

[@waakufaaku9554]

This is math. It's just a formula that's used predominantly in Biology.

[@tapasmazumdar3831]

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.

[@SolvayConference]

Triggered by the word diversity lmfao

[@monkeydoespride]

Bruh, this is a part of AP Bio. Its hella useful
