Statistics - How to calculate the coefficient of variation

In this video I'll quickly show you how to find the coefficient of variation. There are two formulas for samples and populations, but these are basically the same and involve dividing the standard deviation by the mean and lastly converting to a percent. The coefficient of variation is useful for comparing the variation of two groups that have different means, or are measured on different scales.

I searched randomly for this formula and needed it urgently for an MCQ as I am a CA student. Helped me when it was needed. Thanks man

[shenanigansforsure]

My math notes were too complex. This really simplified it for me, thank you!

[gaylelim]

your handwriting is gorgeous and thank you for mentioning up front which formula is for which, because some videos don't, and i get confused. thanks for sharing!

u teach better than my teacher 😭 now i can finally answer my pt

[Graanvlok]

At what point are we supposed to understand this at an intuitive level, or can I get by with just learning formulas and applying them?

[uchihasasuke]

Please correct me if i'm wrong.
Thus, in general if i am not comparing cv's of two groups to see which one is more diverse,
My CV of a group tells me on average how much percent an entry of my group differs from any other entry within that same group.
Am i right ?

Great explanation man ..could u please tell me from which country u are belong with

[aravindsunil]

Can we divide it by median instead of mean ?

[vrixwembly]

Our teacher gave us 3 sets of population. Am I supposed to add all the SD and mean from each population and come up with one CV ? Or each set shall have one CV? Thanks.

Sir which calculator you using ? name, model no, & price & where it'll available ?

[johnnydripdrip]

Wow...That was really helpful. Thank you

[jamesschower]

Great Video, I got it with your demonstration.

[VocalVoltage]

I love you brother hanks for helping e out! love from

[beaangelnicolemendoza]

Hi! How can we know if we should use the sample or population? (even if they have the same formula) thanks!

[vanshikasingh]

me watching this a minute before my exam :0









I passed. thanks!

Your standard deviation values are wrong

[samdillinger]

With respect to this formula whats considered high and low. So if its under 1 the data is close to the mean and higher than one its spread out from the mean right?

I understand this in the first seconds tnx from morroco

[Itx.nory]

Sir can you please solve this question
""What do you say about the relative dispersion of 5, 5, 5, 5? ""
