Accuracy vs Precision - What's the Difference?

Accuracy and Precision are terms that most people use interchangeably in normal life. But when it comes to statistics and quality management, they have a very distinct meaning. Accuracy is about values being close to the true or target value, whereas Precision is about values being close to each other (less scatter). The concepts are really simple to grasp if you get to see a few good examples. If you are preparing for the PMP or CAPM certification you should clearly understand the difference between Accuracy and Precision before you go for the exam.
