Accuracy refers to the closeness of a measured value to a standard or known value.
This concept is important as bad equipment, poor data processing or human error can lead to inaccurate results that are not very close to the truth.
Formula to calculate accuracy.
So as to know how accurate a value is, we find the percentage error.
Suppose the known length of a string is 6cm, when the same length was measured using a ruler it was found to be 5.8cm. Calculate the accuracy of the ruler.
100% – 3% = 97%
Therefore, the results are 97% accurate.
