Meaning of Mode
- The mode is the observation that occurs most often in a set of data.
- It is a measure of central tendency, like the mean and the median.
- The mode is always one of the values in the data set itself.
Common mistake: Writing the frequency (how many times it appears) as the answer instead of the observation that appears most often.
Counting Frequencies Carefully
- The frequency of a value is the number of times it appears in the data.
- Arrange the data in ascending order or make a tally table so equal values sit together.
- Compare all frequencies and pick the value with the largest one.
Common mistake: Missing a repeated value scattered in an unsorted list, which makes its frequency too small and gives the wrong mode.
Data With More Than One Mode
- A data set can have more than one mode.
- If several values share the same highest frequency, each of them is a mode.
Common mistake: Choosing the largest value, or the value that appears first, instead of the value with the highest frequency.
Exam tips
- Sort the numbers first, then count each group of equal values.
- Check that your frequencies add up to the total number of observations.
- The mode need not be the middle value or the biggest value. It depends only on frequency.

Sample questions
What is the mode of the following set of numbers: 3, 5, 3, 7, 9?
Show answer
Answer: A. 3
The mode is the number that appears most frequently in a data set. Here, the number 3 appears twice while the others appear only once.
Which of these numbers is the mode of the following dataset: 8, 8, 7, 6, 6, 6, 5?
Show answer
Answer: B. 6
The mode is 6, as it appears three times in the dataset, which is more than 8 or any other number.
What is the mode of the dataset: 15, 15, 20, 20, 20, 25, 30?
Show answer
Answer: B. 20
The mode is the value that appears most often. In this set, 20 appears three times, more than any other value.
From the set {2, 3, 3, 5, 5, 1, 4, 4, 5}, what is the mode?
Show answer
Answer: D. 5
5 appears three times, more than any other number in the dataset, and thus it is the mode.
In the list {20, 20, 21, 20, 22, 23, 23}, what is the mode?
Show answer
Answer: A. 20
The mode is 20, appearing four times in the set, the most of any number.
