alleryReport the most frequent members of the series 1,1,2,3,3,4.
- Only the value 3
- Both 1 and 3
- Both 2 and 4
- Only the value 1
Show answer and solution
Correct answer: B. Both 1 and 3
The values 1 and 3 each occur twice, the joint maximum frequency.

Worked practice questions
For 1,2,3,4, which statement about a unique mode is valid?
- There is no unique mode
- Only 4 is the mode
- The unique mode is 2.5
- Only 1 is the mode
Show answer and solution
Correct answer: A. There is no unique mode
All four values have the same frequency, so no single value is uniquely most frequent.
For the values 1,1,3,7, which measure is greatest?
- Arithmetic mean
- All three equal
- Median value
- Modal value
Show answer and solution
Correct answer: A. Arithmetic mean
The mean is 3, the median is 2 and the mode is 1.
