Experiment 5-Data Anolysis for Accuracy and Precision - A second group of students performed the experiment to determine the percentage of sugar Bazooka chewing gum. The student's results were 55.5%, 66.5%, 66.2%, and 66,7%. Should the students take the average of all four measurements? Why or why not? Will including the measurement affect the accuracy, precision, or both - why?

Experiment 5-Dota Anolysis for Accuracy and Precision
3. A second group of students performed the experiment to determine the percentage of sugar in
Bazooka chewing gum. The student's results were 5.5%, 66.5%, 66.2%, and 66,7%. Should the
students take the average of all four measurements? Why or why not? Will including the
measurement affect the accuracy, precision, or both - why?

4. A third group of students performed the experiment to determine the percentage of sugar in Bazooka
chewing gum. The results were 62.5%, 68.5%, and 62.5%, and 67.7%. The mean is 65.3%. The
average deviation is 2.8%.
(a) Calculate the RAD in ppt. (show equation). Based on the RAD, how precise where the students?
Explain.
(b) Assuming the theoretical value of sugar in Bazooka chewing gum is 66.7%, calculate the student's
percent error (show equation).
(c) Compare the precision and the accuracy. How would you describe the data? Explain.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F00996d7a-df3c-4dd3-8bb6-485e7aa538d1%2F7289b77e-273f-45ea-98a5-bb4efe98da4a%2Fmfpnwwr_processed.jpeg&w=3840&q=75)
