    STANDARD DEVIATION

    answer

    standard deviation is a measure of the dispersion of a statistical sample, equal to the  square root of the variance.  To compute the standard deviation, compute first the mean score

    Solution :  

    Step 1. compute the  Mean score

    Mean = (∑▒x)/n

    Mean = (7+ 7+8+12+ 14+ 14+ 14+ 14+ 15+ 15)/10

    Mean = 12

    xmean  x - mean(x - mean)^2    

    712-525    

    712-525    

    812-416    

    121200

    Standard deviation: √((x - mean)^2)/N  )

    Standard deviation: 100/ 10 Standard deviation =10
