💡 Analysis & Explanation

Statistical Definition ▼

In basic statistics, the 'mode' of a data set is strictly and simply defined as the specific value that appears most frequently (has the highest occurrence).

Frequency Counting ▼

Let us systematically tally the occurrences of each unique number in the provided array. The digit '1' appears twice. '7' appears twice. '8' appears twice. '4' and '5' both appear merely once.

Identifying Highest Occurrence ▼

Counting the digit '3', we find it distinctly scattered throughout the sequence exactly 7 times. It vastly outnumbers any other digit's frequency.

Conclusion ▼

Because it has the highest frequency of occurrence, the mode is clearly 3.
