A boxplot can be said to be a standard method of displaying the distribution of data.
A boxlot has 5 number summaries which are:
• The minimum data
,• The First quartile (Q1)
,• The median
,• The third quartile (Q3)
,• The maximum data.
In a boxplot, the Inter Quartile Range is gotten by subtracting the First quartile (Q1) from the third quartile (Q3).
IQR = Q3 - Q1
The IQR indicates the length of the box.
A bigger box indicates a bigger IQR, while a smaller box indicates a smaller IQR.
Therefore, the correct statement is:
The bigger the ''box'' is the larger the IQR.
ANSWER:
C. The bigger the ''box'' is the larger the IQR.
