what is accurate

According to the Merriam-Webster dictionary, "accurate" means "free from error especially as the result of care". Other dictionaries, such as the Cambridge English Dictionary and Dictionary.com, define "accurate" as being correct, exact, and without any mistakes. Accuracy is a measure of how close a given set of measurements are to their true value, while precision is a measure of how close the measurements are to each other. In scientific and technical contexts, accuracy and precision have distinct meanings, but in everyday language, they are often used interchangeably. An accurate instrument or measurement is able to give information that is correct to a very detailed level. An accurate statement or description is one that is true and without errors.
