So there is this question:

Attachment:

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

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.

Thank you
