For example: John recorded the number of houses that were decorated with holiday lights on different blocks in his neighborhood.
Which was the most common interval for the number of decorated houses?
Solution:
From the above histogram, we get the following information:
Number of blocks in the interval 0-4: 2
Number of blocks in the interval 5-9: 8
Number of blocks in the interval 10-14: 5
Number of blocks in the interval 15-19: 1
8 is the greatest number among 2, 8, 5, 1.
Therefore, the most common interval for the number of decorated houses is 5-9.
