In finance, economics, and statistics, percentage points are used to express the change in a rate or ratio. A common question that arises is whether to use "percentage point" or "percentage points" when referring to a change of 0.1. In this article, we will explore the correct usage of both terms and provide examples to illustrate the difference.
What is a Percentage Point?
A percentage point is a unit of measurement that represents a change of 1% in a rate or ratio. For example, if an interest rate increases from 5% to 6%, it has risen by 1 percentage point.
What are Percentage Points?
Percentage points are the plural form of percentage point. It refers to multiple units of measurement, each representing a change of 1% in a rate or ratio.
0.1 Percentage Point or Points?
Now, let's consider the question of whether to use "percentage point" or "percentage points" when referring to a change of 0.1.
- 0.1 Percentage Point: This is the correct usage when referring to a change of 0.1%. For example:
- The interest rate has decreased by 0.1 percentage point to 4.9%.
