    xi|d|=(xiMean)d2351316924245765241653525568645810100524165021651394911480980

    ¯¯¯¯¯X=1nxi=110[480]=48

    var (x) = 1n{(xi¯¯¯x)2}=110{980}=98

    S. D (x) = var(x)=98=9.9

    Coefficient of variation = S.D¯¯¯¯¯¯X1×100=9.948×100=20.6

    xd=(xMean)d235131692424576524165352556864581010052416502451394911480980

    ¯(x)=1nxi=110[1050]=105

    var(x) = 1n{(xi¯¯¯x)2}=140{40}=4

    S.D .(x) = var(x)=4=2

    Coefficient of variation for shares Y=S.D¯¯¯¯X×100=2105×100=1.90

    Since the coefficient of variation for shares Y is smaller than the coefficient of variation for shares X, they are more stable.
