The following box plot represents the average heights of the students in Mr. Taylor's fourth grade math class. What is the median of this data set? What is the interquartile range of this data set?

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
