Which unit of measurement is more accurate?

The second measurement is more accurate because the error is smaller when compared with the actual measurement. Consequently, for any specific measuring tool, one can be equally precise with the measures. But accuracy is often greater with larger objects than with smaller ones.

What determines the precision of a measurement?

The precision of a measuring tool is related to the size of its measurement increments. The smaller the measurement increment, the more precise the tool. Significant figures express the precision of a measuring tool.

Is there a difference in the accuracy of measurements of the reading if the units used vary?

Yes, there is a difference.

What is accuracy in measurement?

Measurement accuracy is defined as the closeness of agreement between a measured quantity value and a true quantity value of a measurand (i.e., the quantity intended to be measured) (ISO-JCGM 200, 2008), and is often limited by calibration errors.

Which standard has highest accuracy?

Explanation: Universal measuring instrument is of the highest accuracy due to the presence of sensors, micro switches and microprocessors.

How do you know if a measurement is accurate?

Accuracy refers to the closeness of a measured value to a standard or known value. For example, if in lab you obtain a weight measurement of 3.2 kg for a given substance, but the actual or known weight is 10 kg, then your measurement is not accurate. In this case, your measurement is not close to the known value.

Is there a difference in the accuracy of measurements?

Both accuracy and precision reflect how close a measurement is to an actual value, but they are not the same. Accuracy reflects how close a measurement is to a known or accepted value, while precision reflects how reproducible measurements are, even if they are far from the accepted value.

What is an example of both accurate and precise?

Accurate and precise: If a weather thermometer reads 75oF outside and it really is 75oF, the thermometer is accurate. If the thermometer consistently registers the exact temperature for several days in a row, the thermometer is also precise.
