Question

How do you make a box-and-whisker plot of the data 24, 18, 29, 21, 16, 23, 13, 11 ?

Answer 1

Answer:

Step-by-step explanation:

Arranging the data set in ascending chronological order:

11, 13, 16, 18, 21, 23, 24, 29

Establishing the quartiles (average):

Q1=1/2(13+16)= 14.5

Q2=1/2(18+21)= 19.5

Q3=1/2(23+24) =23.5

Thus, the box plot contains 5 numbers where -

Minimum number = 11

q1 = 14.5

Median or q2 = 19.5

q3 = 23.50

Maximum number = 29

Answer 2

Answer:

A Box and Whisker Plot (or Box Plot) is a convenient way of visually displaying the data distribution through their quartiles. The lines extending parallel from the boxes are known as the “whiskers”, which are used to indicate variability outside the upper and lower quartiles.
