So there is this question:

The table shows the results of a poll which asked drivers how many accidents they had had over the previous 5 years. What is the median number of accidents per year?

A. 0.5
B. 1
C. 1.5
D. 2
E. 4

And here a sample answer:

Total Number of Drivers : 17 +13 + 21 + 4 + 2 + 2 + 1 = 60
So, the median number of accidents per year should be between the 30th and the 31st driver
The 30th driver had committed 1 accident
The 31st driver had committed 2 accidents

The median = 1+2 /2 = 1.5 accidents per year

Option C


Isn't there a problem with the question? Shouldn't it be "What is the median number of accidents per driver?". As 1,5 accidents per year doesn't make much sense.

What are your thoughts?

Thank you
