Based on the numbers above what is the variance and the standard deviation of the data set.

I think 616.2 is the variance

I think 24.83 is the standard deviation

Am I correct????

    When page be open in rectangle type :

    variance {13,14,29,26,41,53,60,7,89,14}

    and click option =

    Then in rectangle type :

    standard deviation {13,14,29,26,41,53,60,7,89,14}


    The variance = 685.156 approx. 685.2

    The standard deviation = 26.1755 approx. 26.18
