Nine students wrote down how many books they read last month: 2, 4, 4, 5, 6, 4, 7, 8, 4. The librarian states: 'Both the mode and the median of this data are the same number.' Is the librarian correct, and what is that number if so?

Question

Accepted Answer

Yes, both are 4. Mode: 4 occurs 4 times, more than any other value, so mode = 4. Order: 2, 4, 4, 4, 4, 5, 6, 7, 8; there are 9 values, so the 5th (middle) value is 4, giving median = 4. Both the mode and median are 4, so the librarian is correct.
