    In order to draw the Box-whisker plot, we need to rewrite the data in increasing order.

    42 43 47 48 51 52 56 56 58 60 62 64 65 66

    Mean of the data = (42 + 43 + 47 + 48 + 51 + 52 + 56 + 56 + 58 + 60 + 62 + 64

    + 65 + 66) : 14

    Mean of the data = 770 : 14

    Mean of the data = 55

    Median = (56 + 56) : 2

    Median = 112 : 2

    Median = 56

    Lowest value = 42

    Highest value = 66

    Range = Highest value - Highest value

    Range = 66 - 42

    Range = 24

    Lower Quartile = 25% of the data

    Lower Quartile = 48

    Upper Quartile = 75% of the data

    Upper Quartile = 63
