If you make rough or approximate measurements when doing experiments , you will get a rough and approximate answer, won't you!. For any information to be useful, it must be accurate and reliable. What would happen if bridge designers used the results of steel strength tests, which were approximate or just slightly wrong? ANSWER: there would be either, far too much expensive steel used to make the bridge, or there would be a slight mishap, such as a few dozen loaded trucks falling into the river. If you are a Scientist or a design Engineer, you must be thorough and very very accurate with everything you do. People that manufacture things , such as Medicines, and Cars, and Clothing, and Houses, and anything you can think of; must measure, or weigh everything very very accurately otherwise people die. Sloppy workers and rough careless workers are useless and dangerous people, and they can cause the death of innocent people.
Accuracy, precision, repeatability and so on are terms that have been closely defined for measurement purpose. By folk such as ASTM. and ISO.The true value is the value towards which a large number of different measurements (by different measurement teams, using different measuring systems ... ..) tends.The accuracy of a particular method or measurement is how closely that answer comes to the True Value.The precision of a measurement represents the confidence you have in the measurement. (Generally by making several measurements.)The resolution of a measurement is merely the number of figures in your answer. A number with many places would have greater resolution, but many of those numbers might be meaningless.So, a single measurement of the height of a mountain for example, might be correct, (true value) but you don't necessarily have reason to be confident of the answer.
because they are both a reliable measurement and is both accurate and precise
Because if you add to much of that ingredient Like for example you add to much milk to pancakes it would be super watery so that is the reason why to be accurate ;D

Eye-Balling? Rough Guess? Educated guess?
because they are both a reliable measurement and is both accurate and precise
Accuracy is important to ensure that the measurement is as close to the true value as possible, while precision is important for ensuring consistency and reliability in repeated measurements. Having both accuracy and precision allows for confidence in the validity of the measurement and the ability to replicate it reliably.

Precision is important in measurement because it reflects the degree of accuracy and reliability in a measurement process. It helps in minimizing errors and variations in data, providing consistency and repeatability in results. High precision ensures that measurements are closer to the true value, making the data more trustworthy and useful for decision-making.
Optical measurement is important because it allows for non-contact and non-destructive measurement of physical properties like dimensions, shape, surface roughness, and color. It offers high precision and accuracy, making it valuable in various industries such as manufacturing, healthcare, and research. Optical measurement also allows for rapid data collection and analysis, enabling quick decision-making and quality control processes.

Measuring with accuracy and precision is important to ensure that data and results are reliable and can be trusted. Accurate measurements reduce errors and inaccuracies, leading to more valid conclusions and better decision-making. Precise measurements enable consistency and reproducibility in experiments, allowing for comparisons and reproducibility of results.

False. In addition to reproducibility, accuracy, precision, and validity are also important when making scientific measurements. Reproducibility ensures that the results can be consistently obtained by different researchers, while accuracy refers to how closely the measured value aligns with the true value. Precision relates to the consistency and reliability of the measurements, while validity ensures that the measurements are actually measuring what they claim to measure.

Yes, a micrometer typically offers higher precision compared to a vernier caliper, making it better suited for measuring the diameter of small objects like rods with greater accuracy. If the diameter measurement requires a high level of precision, using a micrometer would be a preferred choice.
