Simpson's Diversity Index Explained

[@danielacastellanos6795]

I needed this video so bad! Thank you for simplifying my teacher's overcomplicated explanations

[@yjwsonly8106]

bro explained it better than my teacher🤷‍♀️

[@dianitasusilosaputri6703]

when should we use simpson index and when should we use simpson reciprocal index? please make an explanation video for shannon diversity as well. thank you

[@BelabedRami]

Im doing my thesis on a botanical site study. Im having a real hard time calculating the number of species present and how to differentiate between them (especially the pinaceae family) any advice?

[@nicolealexander5394]

Thank you! This really helped my visualize and simplify this! My lab is going to be much easier now.

[@joshbamber9902]

For one area I had 15 organisms with 8 species, I got 6.17 for that one For another area I had 3 organisms with 2 species, I got 3 Could you tell me what this infers and why as I’m sure I’ve done the method wrong

[@finleykendall7718]

Very explained, thank you !!

[@kelebekaan2826]

With this index, can I reveal how species diversity in an ecosystem changes over time?

[@Science_Sauce]

Yes. If you repeat the process at different points in time it tells you the change.

I really thought that when I am gonna use another variation of SDI, I'll gonna get the same results but I am wrong. Now I am even more confused :(((

[@aranea_]

where did the 210 come from?? and why was it 210 and where to find it??? please reply

[@Science_Sauce]

N = total number of organisms = 15. “N(N-1)” = 15 x (15-1) = 15 x 14 = 210

You’re welcome! Happy to help.

[@clovisfilho93]

If I'm not mistaken, you subtract one because you are working with a sample and not the whole population

[@therealanton200]

No, we do not do this because this method is called Simpson's reciprocal index.

[@nikolaimadudes8931]

you divide 210 and 92?

[@sarojkumari2756]

How could you told wrong formula

[@ankushkaundal7465]

Bigger the value of d, lower the diversity... U said greater value of d higher the diversity ..it is lil bit confusing ...can u elaborate

[@Science_Sauce]

There are several versions Simpson’s index - they’re mentioned in the video. This one is Simpson’s reciprocal index and here larger D value indicates greater biodiversity.

[@cortezreyjohno.8440]

Thank You, I am not a bit boiling down to calmness.

[@aneco2687]

I'm afraid you are interpreting the simpsons diversity index wrong. The higher the diversity index D the lower the Diversity. When you calculate 1 - D you can say that a higher value equals a higher diversity.

[@Science_Sauce]

There are several versions of Simpson’s diversity index. This video uses Simpson’s reciprocal index and a higher value indicates higher biodiversity.

@@Science_Sauce so then what does your one range by

[@mono635]

Thank you!

[@ritasrimustikasari]

Thank you.

[@yuchenli9907]

I'm a little confused. The Simpson's Diversity Index equation that I've learned needs to be one minus.

[@Science_Sauce]

There are several versions of Simpson’s index. This one is Simpson’s reciprocal index.
