Question

What is the median of the data displayed in this box-and-whisker plot? A.41 B.49 C.55 D.58

Answer 1

Answer:

Option: A is the correct answer.

The median of the box and whisker plot is:

           A.  41

Step-by-step explanation:

From the box and whisker plot that is provided to us we see that we are given following information:

• Minimum value= 35

• Maximum value of the data is: 55

• Hence, Range of the data set is: Maximum value-Minimum value

                               Range   =55-35=20

• First quartile or lower quartile i.e. $Q_1$ is: 37

• Middle quartile or median of data is: $Q _2$ is: 41

• Upper quartile or third quartile of data is: $Q_3$ is: 49

• Interquartile Range i.e. IQR is: $Q_3-Q_1$

                                              =  $49-37$

                                      IQR = 12

                        Hence, the median is:   41

Answer 2

The median in a whisker plot is the dot or line in the box on the line. In this case, the dot is at 41, so the median is 41.

ANSWER: A) 41 is the median
