Answer:

Thanksgiving, median = 17

New year's eve, median = 8

Thanksgiving, IQR = 12

New year's eve, IQR = 10

THANKSGIVING has greater variability

Explanation:

The median value of a box plot is the line which lies in the middle of the box :

From the plot, the best estimate :

Thanksgiving, median = 17

New year's eve, median = 8

THE Interquartile range, IQR is the difference between the upper quartile and lower quartile values, Q3 - Q1 ;

Lower quartile = the starting point of the box

Upper quartile = the endpoint of the box

From the plot ; Best estimate :

Thanksgiving :

Q1 = 12 ; Q3 = 24

IQR = Q3 - Q1 = 24 - 12 = 12

New year's eve :

Q1 = 5 ; Q3 = 15

IQR = Q3 - Q1 = 15 - 5 = 10

Thanksgiving :

Range = Maximum - Minimum

Range = (29 - 5) = 24

New year's eve:

Range = Maximum - Minimum

Range = 22 - 3 = 19

Hence, Thanksgiving has greater variability
