Lesson Transcript
Instructor: Karin Gonzalez

Karin has taught middle and high school Health and has a master's degree in social work.

Learn the definition of accepted value in terms of accepted value versus experimental value, as well as the formula associated with accepted value, experimental value and percentage error. Then take a brief quiz to test your new knowledge.

What Is Accepted Value?

The term accepted refers to something that is agreed to be correct by most people. For example, it is an accepted idea that if someone eats nutritiously and exercises regularly, they will maintain a good weight. It is also an accepted idea that getting about 8 hours of sleep each night will leave you adequately rested and alert for the rest of the day. In terms of science, it is accepted that the earth is round and that gravity is what keeps us grounded to our planet.

Similarly, accepted value is a term often used in science or mathematics to mean the value of something that is regarded as true among all scientists or mathematicians. This is different from experimental value, which is the value that results from an individual's laboratory experiment or an individual's calculation. Accepted value is often referred to as theoretical value.

Accepted Value Examples

Let's look at a few examples.

Example 1:

The accepted value of the temperature at which water boils is 212 degrees F. It is accepted because in experiment after experiment, scientists have all come to the conclusion that this is the exact temperature that water needs to heat up to in order to start boiling.

Example 2:

An accepted value could also refer to something as simple as someone's height. An adult's height in inches is an accepted value among anyone who has ever measured that person's height- doctors, nurses, and family members, among others- because it is accepted by every individual that has measured that person's height, as well as that particular person.

Accepted Value vs. Experimental Value

To understand the difference between accepted value and experimental value, let's look again at our example about the boiling point of water. Mrs. Jones' middle school chemistry class is expected to form lab groups A, B, C and D to find the temperature at which water boils in today's experiment. Mrs. Jones knows that the accepted value of boiling water is 212 degrees F, but she wants to wait to tell the class until they complete their experiment to prevent experimenter bias. Here are the results from the experiment:
