    Modified Boxplot

    Data: 0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,1,2,2,4,5,5,5,6,6,8, 9,9,9,10,16

    Draw a modified boxplot of this data (find the median, upper & lower quartile values and the interquartile range, also any outliers if applicable)

    I know the median is 0.5
    Lower quartile 0?

    Q1=0, Q2=0.5, Q3=5.5

    IQ=5.5

    Q1-1.5*IQ = -5.5
    Q3+1.5*IQ = 13.75

    So there are no lower outliers, and 16 is the only upper outlier.
