Accuracy and Precision in Measurement Purpose: To calculate measurements like density, temperature, volume and mass through experimentation. Test accuracy and precision of collected data by calculating absolute deviation, average deviation, uncertainty and percent error. Conclusion: There was a 7% error in the value recorded for volume of cylinder. A 25% error was calculated in the density of the metal balls. Errors could have occurred due to inaccurate measurements (amount of water used, or the reading on the graduated cylinder not read accurately). It is essential to use the same degree of accuracy for all values in order to obtain accurate results. It is not necessary for measurements that are accurate to be precise.
