Accuracy is to do with how close the result you obtain is to the true result. For example, if you try to measure the boiling point of water, and you get 93 degrees Celsius as your answer, it's not very accurate. So, you've made an accuracy error, which could have been caused by any number of factors in the setup of your equipment (e.g. faulty thermometer).
Precision is to do with how many significant figures you've measured your answer to. For example, if your temperature result game to 99.884 degrees Celsius, then you've probably been too precise with your measurement.
How's that?
