Question

The frequency table below will be used to make a histogram. What ia an appropriate scale and interval for this histogram?

A. The scale shod be 0 - 10, and interval should be 10

B. The scale should be 0 - 15, and interval should be 5

C. The scale should be 1 - 10, and interval should be 5

D. The scale should be 1 - 15,and interval should be 10​

Answer 1

D

Explanation:

Answers A and C are cancelled immediately because 71-80 has 11 number of students, thus the scale cannot be 0-10 since that would mean the data for test scores 71-80 to be cut off

The answer is not B because the having 5 as the interval is too low and would make the histogram stretch out when 10 can make it shorter and look nicer.
