Accuracy and Precision

This chemistry video tutorial explains the difference of accuracy and precision in measurement. This video gives an example of four students attempting to measure the density of aluminum and asks which data is accurate but not precise. Accuracy has to do with how close your data is to the accepted value and precision has to do with how close your data is with each other.
