What is a sample and example?

A sample and an example are similar concepts that both refer to something that represents a larger whole, but they have slightly different uses and nuances. A sample is a small physical portion, specimen, or subset taken from a larger whole for testing, analysis, demonstration, or trial. For instance, a blood sample is a small amount of blood taken to test health, a free sample of perfume is a small vial to try, and a statistical sample is a group of people selected from a larger population to study. An example is something that illustrates, explains, or demonstrates a concept, category, or rule, used to clarify meaning. For instance, an example sentence shows how to use a word, an example of a mammal is a dog. So a sample is often tangible and taken from the actual whole it represents, while an example can be any illustration that clarifies a concept, not necessarily a physical piece of the whole. However, all samples can serve as examples of the whole they come from, and in everyday language the words are often used interchangeably when offering a demonstration, like try a sample or example of this cake. The key difference is sample emphasizes physical representation and testing, while example emphasizes illustration and explanation.
