    CV = s/mean
    A) 2000/120000 = .016
    B) 10000/900000 = .011
    So sample A has more variation
    The CV is particularly useful when you want to compare results from two different surveys or tests that have different measures or values. For example, if you are comparing the results from two tests that have different scoring mechanisms. If sample A has a CV of 12% and sample B has a CV of 25%, you would say that sample B has more variation, relative to its mean.(Copied)

      Thank you very much man , i think you completed the video and gave the main idea . 👌👍

      CV= (s/mean) x 100

    I was here to find out about Coefficient of Variation but you gave me a new understanding of standard deviation

    As incomplete as it may be, I still believe the man made some sense of this

    Coefficient of variation shows you the degree at which the data varies. It is CV=100 times stdev/mean.
    In this case nh1 CV is 1.667 and nh2 CV is 1.111. This means nh1 has a great degree of deviation.

      Your answer is correct, but your formula is wrong. CV=(Std dev/mean)*100.

      @@cottonbrad He has used the correct formula he has just written it in words.
      So he written it as 100 times Stdev/mean
      You are saying it as CV= SD/MEAN *100 which also means the same.

    Coefficient of variation for :
    N.H # 1: CV= S.D/Mean * 100
    therefore CV = 2,000/120000*100
    = 1.67
    N.H # 2: CV = 10,000/900,000*100
    =1.11
    Therefore, N.H#1 has more spread as compared to N.H#2

    Hi, great video. Unfortunately it didn't address my problem. I have computed several std of the same variable for different samples. So I have one std per sample. How could I compare them and determine whether they are statistically different? Or that they differ up to a percentage? Thank you!

    CLICKBAITTTTT
    The title says what is Coefficient of Variance, you have said everything except anything related to the title of the video. I get it you are trying to sell your DvDs but when someone reads the title and wastes his 5 mins around the exam corner, that person will just swear at you for wasting his time.
    Btw the formula is CV= standard Deviation\mean * 100
