2. The data 5, 8, 5, 9, 8, 11 has how many modes?
- A0
- B1
- C2

Show answer
Answer: C) 2
5 appears twice and 8 appears twice (both maximum). So there are two modes (bimodal).
3. What is the median of the first five even numbers 2, 4, 6, 8, 10?
- A7
- B12
- C5
- D6
Show answer
Answer: D) 6
Five ordered values; the 3rd (middle) value is 6. Median = 6.
4. Eight observations are: 3, 7, 7, 9, 11, 13, 13, 15.
Notice both 7 and 13 occur twice.
How many modes does this data have?

Show answer
Answer: C) 2
Both 7 and 13 occur twice, which is the maximum frequency. So the data has 2 modes (it is bimodal).
5. 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?
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?
- ANo, mode is 4 and median is 5
- BYes, both are 5
- CYes, both are 4
- DNo, mode is 4 and median is 6
Show answer
Answer: C) 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.
