Chemistry and Society According to the Merriam-Webster Dictionary‚ accuracy is “freedom from mistake or error: the quality or state of being accurate: the ability to work or perform without making mistakes” ("accuracy‚" 2014). Precision‚ however‚ is “the quality of being precise” ("precision‚" 2014). That doesn’t really help with the definition much. After subsequently checking the definition for precise it means to be “very careful and exact about the details of something” ("precise‚" 2014). The
