What is accuracy give some example?

Answer 1

Accuracy refers to how close you are to the real answer. This is usually used in measurements. For example: The weight is 55.5kg. The accurate measurement will be 60kg which is close to the real answer.

Answer 2

Accuracy is obtaining a result close to the 'known' value or the correct answer. An example of accuracy is shooting thee arrows and having them all be clustered around the bull's eye. This should not be confused with precision, which is the agreement between the various measurement (ie one could shoot all the arrows in a close cluster away from the bull's eye, and this would be high precision but low accuracy).

Answer 3

Accuracy refers to the degree of conformity between a measured or observed value and the true or accepted value. For example, if a scale measures your weight as 150 pounds when your actual weight is 155 pounds, the scale has an accuracy issue. Similarly, if a thermometer consistently reads 2 degrees higher than the actual temperature, it has an accuracy problem.
