  1. Median = 140 cm

    Interquartile range = 3cm

    Step-by-step explanation:

    =>The median value of a data set is usually represented by the vertical line that divides the rectangular box in a box plot.

    Therefore, the median value of the data set in the box plot above = 140 cm

    =>Interquartile range is the difference between the upper quartile (Q3) and lower quartile (Q1) of a data set.

    Upper quartile (Q3) is indicated at the end of the rectangular box in a box plot, to our far right, while the lower quartile is indicated at the beginning of the rectangular box to our left.

    In the data set above,

    Q3 = 141

    Q1 = 138

    IQR = 141 - 138 = 3 cm
