CHE 120 Activity 2. Measurement Evaluations: Accuracy & Precision Associated Resources: Accuracy & Precision Handout Exercice #1: Two students weigh a powdered metal, 1: Wo students weigh a powdered metal and report the results of their multiple trials below. The exact (true/accepted) value for this mass is 8.72 9. Student #1: 8.72 g: 8.74 g: 8.70 g Student #2:8.50 g: 8.48 g: 8.519 a) Calculate the average mass from each set of data Average Set 1: _ Average Set 2:...
Explain the difference between precision and accuracy. Also illustrate that difference with a schematic representation.
Part 2: Accuracy vs Precision The objective of this exercise is to understand the difference between precision and accuracy in a series of measurements. Equipment Virtual Bull's Eye (2 sheets with Carbon paper in between) Procedure Part A )Imagine that you lace the Bull's Eye on the floor, and then t drop a small ball from a 2-meter height (say, extending your arm above your head), aiming at the center of the target 2) The ball, hitting the carbon paper,...
Consider this statement: "The variation between groups was 3.7%." Is this statement discussing accuracy or precision? Briefly explain why you chose your answer.
From a set of samples, can we directly calculate estimates of accuracy and/or precision? Explain why?
