Accuracy refers to a lack of mistakes or errors. "I type very fast, but the accuracy of my typing is n't very goode."
Accuracy is a must for anyone who works in a precise profession. Would you trust a surgeon who lacks accuracy to remove your appendix? His lack of precision might result in the accidental removal of your spleen. A meteorologist with questionable accuracy isn't going to be popular either, especially when it rains every time he predicts a sunny day.
