Front

What does Precision mean in measurements?

Back

Precision refers to the consistency of repeated measurements, indicating how close the measurements are to each other, regardless of whether they are close to the true value.

Front

What is the difference between Accuracy and Precision?

Back

Accuracy is about how close a measurement is to the true value, while precision is about how consistent the measurements are with each other.

Front

What is a significant figure?

Back

Significant figures are the digits in a number that contribute to its precision, including all non-zero digits, any zeros between significant digits, and trailing zeros in the decimal portion.
