Using the data you collected, which ruler gave you the most precise measurements of volume? Which of the two methods for measuring the volume of the rubber ball is more accurate? Which method is more precise? Explain this using your data. Did the accuracies of the calculations of volume and of density depend upon the precisions of the instruments used? Explain using your data. Was the method of measuring time with the stopwatch more precise or more accurate than measuring time by using the sensors? Explain using your data. What factors might have contributed to the uncertainty of time measurements when using the stopwatch?
