Key Differences
"Percentage" and "Proportion" both quantify relationships, but in distinct manners. A "Percentage" is a specific type of proportion expressed on a scale of 1 to 100. "Proportion," on the other hand, defines a general relationship between two quantities.
Consider a group of students in a class. The "Percentage" might describe how many of them passed an exam out of 100, while the "Proportion" could describe the ratio of those who passed to those who did not.
"Percentage" always has a denominator of 100, making it easily relatable and interpretable. "Proportion" is more flexible, denoting a relationship which might not always be out of a specific number.
For businesses, understanding the "Percentage" of market share can provide a clear metric of performance in relation to competitors. Conversely, the "Proportion" of sales between different products helps visualize how each product is doing in relation to the others.
A critical thing to note is that while every "Percentage" is a proportion (since it represents part-to-whole relationships), not every "Proportion" is a percentage since it may not be out of 100.
