When we talk about percentages, it is important to understand the related terminology. The phrase "defined by percentage" can be replaced with synonyms such as "expressed in proportion", "quantified by ratio", "measured by percentile", and "calculated by fraction". These synonyms reflect the idea of comparing a part to a whole, or expressing a value as a percentage of a total amount. Other related terms include "percentage point", which is the difference between two percentages, and "percentile rank", which shows the percentage of values that fall below a certain point in a distribution. Understanding these concepts and their synonyms is important when working with data and interpreting statistical information.
