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
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.
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
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?
@@Science_Sauce OOOHHHHHHH SO THAT'S HOW YOU GOT IT,THANK YOU VERY MUCH!!! NOW I CAN FINISH MY ACTIVITIES FOR TODAY!!! YOU JUST GAINED A SUBSCRIBER 🥰💓💓
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.
I needed this video so bad! Thank you for simplifying my teacher's overcomplicated explanations
bro explained it better than my teacher🤷♀️
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
Thank you! This really helped my visualize and simplify this! My lab is going to be much easier now.
Very explained, thank you !!
Thank You, I am not a bit boiling down to calmness.
If I'm not mistaken, you subtract one because you are working with a sample and not the whole population
No, we do not do this because this method is called Simpson's reciprocal index.

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
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
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 :(((
How could you told wrong formula
Thank you!
Thank you.
With this index, can I reveal how species diversity in an ecosystem changes over time?
Yes. If you repeat the process at different points in time it tells you the change.

where did the 210 come from?? and why was it 210 and where to find it??? please reply
N = total number of organisms = 15. “N(N-1)” = 15 x (15-1) = 15 x 14 = 210

You’re welcome! Happy to help.
@@Science_Sauce 😱
THANK YOU SO MUCHHHH
You’re more than welcome!
I'm a little confused. The Simpson's Diversity Index equation that I've learned needs to be one minus.
There are several versions of Simpson’s index. This one is Simpson’s reciprocal index.
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
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.
you divide 210 and 92?
Tysm
You’re welcome.
You sound Caribbean. Where are you from?
North East England
@@Science_Sauce wow. I love your accent
i like your voice
I love you
