Question

Which of the following terms refers to the level of detail of a measurement, such as the number of decimal places to which an amount is measured?

a. accuracy
b measurement
c estimation
d precision

Answer 1

Option D.

Explanation:

Precision refers to the the level of measurement and exactness of a measurement. The mean diference between 'precision' and 'exactness' is that if a measuring device gives consisten measurements it's considered precise, but it's not necessarily accurate.

For example, a measurement of 2.365m is more precise than a measurement of 2.3m, given that 2.365m has more significant figures and was made with an instrument that has higher precision. This doesn't mean that the measurement is accurate, the real value could be 3m for example! ✅
