The formal definition for the mode of a dataset is:
The most frequently occurring observation in the dataset. A dataset can have multiple modes if there is more than one value with the same maximum frequency.
While you may be able to find the mode of a small dataset by simply looking through it, if you have trouble, we recommend you follow these two steps:
- Find the frequency of every unique number in the dataset
- Determine which number has the highest frequency
Example
Say we have a dataset with the following ten numbers:
Let’s find the frequency of each number:
24 | 16 | 12 | 10 | 28 | 38 |
---|---|---|---|---|---|
2 | 1 | 3 | 1 | 2 | 1 |
From the table, we can see that our mode is 12
, the most frequent number in our dataset.
