Science is based on observation and experiment—that is, on measurements. Accuracy refers to how close measurements are to the "true" value, while precision refers to how close measurements are to each other. Accuracy and Precision of a Measurement. Measurements are an important part of physics. Accuracy and Precision Examples: Example #1 of Accuracy and Precision. Accuracy refers to the agreement between a measurement and the true or correct value. Learn the difference between precision and accuracy, which are kind of like measurements of measurement! In this article, let us learn in detail about precision and accuracy. This sections describes four important ideas and establishes the differences between them. If a clock strikes twelve when the sun is exactly overhead, the clock is said to be accurate. Accuracy is how close a measurement is to the correct value for that measurement. Accuracy Vs. Both these terms reflect how close a measurement is to a known or accepted value. Precise means being able to get the same thing over and over. Accuracy. The difference between accuracy and precision is that Accuracy means how close a measured value is to the actual value and Precision means how close the measured values are to each other. Accuracy. Accuracy Vs Precision. When you repeatedly throw an arrow with the aim of hitting the center of the bull’s eye, Accuracy is how close your arrow gets to your target: the bull’s eye center. While precision is the attribute of the calculation to be consistently reproduced. Bull’s Eye! In science accurate results would be results that are close to the expected outcome. Accuracy and precision are two important factors to consider while taking measurements. At the time of taking measurements, these two are always taken into account, due to their utmost importance in the various field, such as science, statistics, research and engineering. Precision refers to the maximum resolution or the number of significant figures in a measurement. In general, a precise measuring tool is one that can measure values in very small increments. For example, let us say that you are … Precision. The first distinction is between Accuracy and Precision. For example, a clock has a precision of 1 s, whereas a stopwatch has a precision of 0.01 s. Whether or not a measurement is accurate does not depend on the precision. Precision vs. Precisely, accuracy is very much close to exactness and correctness while precision lacks a block or two. Accuracy is exactness, validity and perfection. In this case, Precision is when you continue to hit the same spot over and over again and it may not necessarily be the center of the bull’s eye. An important factor in the accuracy and precision of measurements involves the precision of the measuring tool. Accuracy and precision are two words that are used frequently in science but are commonly mixed up. For example, a standard ruler can measure length to the nearest millimeter, while a caliper can measure length to the nearest 0.01 millimeter. Accuracy symbolizes the extent of conformity, whereas Precision indicates the extent of reproducibility. Note that, precision is a separate aspect which is not directly related to accuracy.
