To begin with, let’s understand what an average is. An average is a mathematical concept that represents a central value of a set of numbers. It can be calculated using different methods such as mean, median, and mode. The choice of method depends on the nature of data and the purpose of analysis.
This idiom can be used in various contexts such as statistics, economics, social sciences, sports, etc. For example, we can say “On average, students spend 2 hours per day on homework” or “On average, inflation rate has been 3% over the past decade”. It helps us to make generalizations based on data without getting into too much detail.

The Origins of the Phrase
The origins of the idiom “on average” are not entirely clear, but it is believed to have emerged in the late 18th century as part of the growing interest in statistics and probability theory.

Historical Context
The rise of statistics and probability theory during this period was closely linked to broader social changes such as industrialization and urbanization. As societies became more complex and interconnected, there was an increasing need for tools that could help people make sense of large amounts of data.
At the same time, there was also growing interest in using statistical methods to understand human behavior and social phenomena. This led to new fields such as sociology and psychology that relied heavily on quantitative analysis.

This phrase is often used in conversation and writing to describe a typical or expected outcome based on a set of data or circumstances.

Additionally, consider whether outliers need to be taken into account when calculating an average. By doing so, you’ll ensure that your use of this idiom accurately reflects your intended meaning.
