5. Calculate the percent error for each student in question #4. 6. What can be done when measuring to minimize error and maximize accuracy and precision? Questions: 1. The accepted value for the mass of a steel cube used in a CPS lab assignment is 100.0 g. A CPS student measures the cube 3 different times and obtains the following values: 97.2 g, 97.3 g, and 97.2 g. Is the student accurate, precise, both or neither? Explain. 2. Calculate the percent error for the average mass value obtained by the CPS student in question #1. 3. The accepted value for the length of glass rod used in a CPS lab assignment is 50.0 cm. A CPS student measures the rod and obtains the following values: 49.9 cm, 50.0 cm, 49.9 cm, and 52.1 cm. Is the student accurate, precise, both or neither? Explain. 4. The accepted value for the diameter of a cylinder used in a CPS lab is 12.2 cm. 3 different students measure the cylinder and obtain the following values: 10.5 cm, 13.2 cm, and 11.0 cm. Are the students accurate, precise, both or neither? Explain. 5. Calculate the percent error for each student in question #4. 6. What can be done when measuring to minimize error and maximize accuracy and precision?

###### "Before using Course Hero my grade was at 78%. By the end of the semester my grade was at 90%. I could not have done it without all the class material I found."
— Christopher R., University of Rhode Island '15, Course Hero Intern

### What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

• I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
