    First, find the middle of the data and you get 4 numbers in each side, then find the median for both group: 100,120,130,188 and for 196,220,265,300, for the group 1 that median is Q1 and for the second the median is Q3, now the interquartile range is=Q3-Q1

    so, Q1 = (120+130) / 2=125

    Q3 = (220+265) / 2=242.5

    IQR=Q3-Q1=242.5-125=117.5
