Interpretation:
The terms accuracy and precision needs to be explained.
Concept introduction:
Accuracy is the measure of a degree of closeness of the measured value to its actual value while precision is a measure of a reproducibility of a set of measurements. Accuracy depends on the person measuring while the precision value depends on measuring tool.
Explanation of Solution
Accuracy is the measure of a degree of closeness of the measured value to its actual value while precision is a measure of a reproducibility of a set of measurements. Accuracy depends on the person measuring while the precision value depends on measuring tool. Accuracy can be calculated by using percent error formula while precision determined by the number of significant figures.
