What detemines the precision of a calculated result based on measurement?
The precision of any measurement comes from the equipment being used, instruments that can measure in smaller increments are more precise, as they can measure closer to the true value. For example if you used a ruler to measure the thickness of a wire, you may get a result of 2mm, but if you measure the same wire with a micrometer you may get a result of 1.8mm - the micrometer can measure in smaller increments, so the result is more precise.
What is precision balance?
A precision balance is a type of weighing instrument used to accurately measure the weight of small items or substances. It typically has a high level of precision and can measure weights to very small increments, often to the milligram or microgram level. Precision balances are commonly used in scientific research, laboratories, and industrial settings where precise measurements are essential.
Is vernier caliper used to measure length or mass?
A vernier caliper is used to measure length, not mass. It is a precision measuring tool commonly used in engineering, metalworking, and other fields to accurately determine the dimensions of an object with high precision.
What can be used to measure the mass of a grain of salt?
A precision balance or a microbalance can be used to accurately measure the mass of a grain of salt. These instruments are sensitive enough to measure very small amounts of mass with high precision.
What would you use to measure a pin?
A micrometer or caliper would typically be used to measure the dimensions of a pin, such as its diameter or length, with precision.
Can standard deviation be a measure of precision?
Yes SD is ofcourse measure of precision
What is the measure of exactness?
Precision
Is accuracy or precision related to standard error?
Standard error is a measure of precision.
If you measure a door to be 2.05m tall by 0.8m wide what is the precision of the measuring device?
The precision is 0.05 metres.
Precision is a measure of how close an answer is to the actual or expected?
False
What determines the precision of measurement?
If you measure the same quantity repeatedly, a low variance in the measurements is a sign of high precision.
What unit and tool do you use to measure a patio deck?
Use a tape measure and measure in metres. For greater precision, measure in centimetres.
Does standard deviation give a measure of accuracy or precision?
Standard deviation gives a measure of precision, not accuracy. It quantifies the amount of variation or dispersion of a set of data points around the mean. Accuracy refers to how close a measurement is to the true value, while precision refers to how close repeated measurements are to each other.
A measure of how consistently a result is determined by repeated evaluations is called?
precision
Precision is a measure of how close an answer is to the actual or expected true or false?
