Question

The following stem-and-leaf plot shows scores on a recent literature exam for both Class A and B.

Which class has a larger range of test scores? What is the range for that class?

Please help me

Answer 1

A range of a data is given by the difference between the highest and the smallest value of the data

Class A:
Highest score = 100
Lowest data = 60
Range for class A = 100 - 60 = 40

Class B:
Highest score = 92
Lowest data = 60
Range for class B = 92 - 60 = 32

Class A has the highest range score
