What is the exactness of a measurement?

Answer 1

• A measurement that can be repeated by an independent person or team of investigators.
• A measurement that includes the margin of error and resolution of the measuring equipment.

Answer 2

Accuracy of measurement refers to the degree of precision required of a measurement.... I work about 8 miles away from where I live. For my boss, that 11 kilometres is accurate enough as a measurement.

However, when I cycle that distance I find that the actual distance is 11.4 kilometres. That's accurate enough for me. Now, suppose I tied a string to my front door and rolled it out as I cycled, I might find that the distance is 11.452 kilometres.... that would be extremely accurate

Answer 3

A precise measurement is one which gives you the greatest information, for example, if you are measuring the length of a piece of wood, and it is exactly 23.0147 inches long, that is a precise measurement, as compared to measuring it as being approximately 23 inches long. Accuracy simply means being correct; if something weighs a pound, and you measure it as weighing a pound, that is accurate; if it weighs a pound but you measure it as weighing half a pound, that is inaccurate.

Answer 4

Measurement accuracy is the comparison of a measurement with a common standard. This system is used to discover whether or not a measurement is reliable.

Answer 5

One in which the values obtained may not be the same as each other necessarily, but the average is the same as the true value.

Answer 6

So that measurements and answers that are not accurate aren't spread round the world, I hope that answered your question. if it diddnt then im sorry.

Answer 7

When you use an actual calibrated tool to measure it and not just guess based on appearance...

Answer 8
