In a statistic class, 10 scores were randomly selected with the following results were obtained: 74, 73, 87, 57, 71, 68, 65, 77, 67, 66. What are the inner fences? What is the coefficient of variation?

    Find the mean and standard deviation for your data. Once you calculate those two values, you can use the following formula to find the coefficient of variation:

    CV = (sd/mean) * 100
    ...where sd = standard deviation and * means to multiply.

    I hope this will help.

    Note: CV is the standard deviation expressed as a percentage of the mean.
