a) Find the five-number summary for each class

 

Afternoon class: Evening class:

 

Min= Min=

 

𝑄1 = 𝑄1 =

 

Median= Median=

 

𝑄3 = 𝑄3 =

 

Max= Max=

 

b) Create a box plot for each set of data. Sketch the box plot for the evening class

 

below the box plot for the afternoon class.

 

continued…

 

c) Use IQR (Inter-quartile range) to determine which box plot has the widest spread for the

 

middle 50% of the data? Explain!
