Accuracy is the tendency for a measurement to be correct. A more accurate measurement will be closer to the true value than a less accurate measurement. Precision is the tendency to come to the same measurement under the same conditions on multiple occasions. A precise measurement may not be accurate, but can be reproduced time after time and give the same (or sImilar) result.

How does the last digit differ from the other digits in a measurement?
The last digit in a measurement indicates the level of precision or uncertainty in the measurement. It is typically an estimate and can vary depending on the instrument's precision or the person taking the measurement. The other digits are considered to be more reliable and accurate in conveying the measurement value.
What are the differences between two scales in terms of their weight measurement capabilities?
Two scales may differ in their weight measurement capabilities based on their maximum weight capacity and precision. The maximum weight capacity refers to the heaviest weight that a scale can accurately measure, while precision refers to the smallest weight increment that the scale can detect. Scales with higher weight capacities can measure heavier objects, while scales with greater precision can provide more accurate measurements for smaller weight differences.
How reading differ if screw gauge is used instead of vernier calliper to measure thickness of glass plate?
If a screw gauge is used instead of a vernier caliper to measure the thickness of a glass plate, the screw gauge will provide a more precise measurement due to its higher accuracy and smaller scale increments. The screw gauge operates by turning a precision threaded screw to measure thickness, while the vernier caliper uses sliding jaws. The screw gauge may be more suitable for measuring thinner or more delicate materials like glass due to its higher precision capabilities.
What constitutes a measurement in quantum mechanics and how does it differ from classical measurements?
In quantum mechanics, a measurement involves observing a property of a quantum system, which causes it to "collapse" into a specific state. This differs from classical measurements, where properties of a system are determined without affecting its state.
How does a scienific law differ from a theory?
A scientific law describes a consistent pattern or relationship observed in nature, while a scientific theory explains why and how that pattern or relationship occurs. Laws are generally more specific and precise, providing a mathematical description, while theories are broader explanations based on evidence and experimentation.
How does accuracy differ from precision in a scientific measurement?
A thermometer says the temperature is 34 degrees ceentigrade. The divisions are so close you could only decide it is 34 rather than 33 or 35. So its precision is one degree. If the specification for that thermometer is plus or minus 3 degrees then you only really know it is between 31 and 37. If its precision is plus or minus one degree you know it is between 33 and 35.
How does acceracy differ from precision in scientific measurement?
Accuracy refers to how close the results are to the established (or predicted) values. Experimentally, accurate results are evidence that the procedure worked as expected and that the combined error from all sources (instrumental, environmental, and human) is low. Precision refers to how close the results are to each other. Highly precise results will indicate that the experiment was run (nearly) identically each time, though it will not guarantee accuracy.
If some measurements agree closely but differ widely from the actual value?
Then they have precision but not accuracy.
How does accurancy differ from precision in a scientific measurement?
Consider someone firing a rifle at a target. If their shots centre around the bullseye, they were accurate, even if the scatter is quite large. If the scatter is very small (i.e. all the shots are very clustered) they were very precise - even if that cluster is far from the bullseye. So accuracy: how on target are you. Precision: How much spread is there around the target?
How does the last digit differ from the other digits in a measurement?

How does a parameter and a statistic differ?
A parameter is a numerical measurement of a population; a statistic is a numerical measurement of a sample.
Why is it best for scientists to use the scientific name of an organism instead of a common name?
Using the scientific name ensures clarity and precision, as common names can vary across regions and languages. Scientific names follow a standardized naming system (binomial nomenclature) which helps scientists accurately identify and classify organisms worldwide.
How does CRISPR differ from other methods of genetic engineering in terms of its precision and efficiency?
CRISPR is more precise and efficient than other methods of genetic engineering because it allows scientists to target specific genes with greater accuracy, making it easier to edit and modify DNA sequences. This precision helps reduce the risk of unintended genetic changes and increases the efficiency of the editing process.
How does the project audit differ from the performance measurement control system?
How does the project audit differ from the performance measjrement control system
How do 5.60 meters in 5.6 meters differ?
The values 5.60 meters and 5.6 meters are the same length, with the former expressing the length to two decimal places and the latter to one decimal place. The extra zero in 5.60 helps to indicate the measurement's precision.
Why is it best for scientist to use the scientist name of an organism instead of a common name?
Scientific names never differ among scientists.
