Accuracy and precision
Lesson Outline
List a textbook quality as the density of a substance. Indicate this as the accepted value of 1.59g/cm^3. Show three trials by two groups of students, group A and group B. List the density determined from measurements of mass/uint and calculate the average. Group A average was 1.57 and group B average was 1.70. Determine which group was more accurate and define accuracy as how close a measure value is to an accepted value. Determine that group B's measurements were closer together but more precise. Define precision as how close the series of measurements are to each other. Define error as the experimental value minus the accepted value. Group A's error was 0.02 and group B's 0.11. Elicit the formula to determine % error. Group A was 1.26% and Group B was 6.91%
