ACCURATE, NOT PRECISE a NEITHER ACCURATE NOR PRECISE a ACCURATE & PRECISE a % ACCURATE, NOT PRECISE 8 @ Which unit of measurement will give the most presice result? Centimeters (cm) Meters (m) 0 Millimeters (mm) The precision of our measurements depends on: 0 How careful you measure and t e tools you use. The time of day. How quickly you measure something. Which of these examples show precision, but not accuracy? A pocket calculator that is broken An atomic clock that displays the wrong time to hundredths of a second. 0 A powerful computer that can calculate decimals to 100 places. Which of these examples shows accuracy, but not precision? A pocket calculator that doesn't work. A basketball player who sinks all his shots. 0 A sundial that lets you know that it's about 2:30. Submit Answer Incorrect. Tries 1/2 Previous Tries These are statements regarding the process of measurement. Select all that are True. Taking lots of measurements and averaging them is way of improving the precision of a measurement. Experimental uncertainty is due to three types of experimental error: Random Error, Systematic Error and Human Error: Just by looking at me, you are able to estimate my age to the nearest year. The next nearest estimation by someone else in the class was off by three years. Of precision and accuracy, your estimate has a relatively high accuracy. Systematic error is natural and present to some degree or another in every measurement. Two different pieces of equipment are used to measure the speed of sound under the same conditions. One instrument reads 3452 m/s and the other reads 333.8 m/s. of accuracy and precision, at least one of these instruments has poor accuracy. of the concepts precision and accuracy, the number of signicant digits in a measurement is most closely related to accuracy.
