The average deviation shows how precise a series of measurements are. Compare the preci- sion of the volume measurements obtained using the 25- and I00-mL graduated cylinders. Do these values really represent the precision of the graduated cylinders themselves?

Question

Use the data table to answer the following questions

6. The average deviation shows how precise a series of measurements are. Compare the preci- sion of the volume measurements obtained using the 25- and 100-mL graduated cylinders. Do these values really represent the precision of the graduated cylinders themselves? 7. Assume that the average volume found using the 25-mL graduated cylinder in Part B is the "true" or accepted value of the volume. Calculate the percent error for the average volume of water measured using the 100-mL graduated cylinder. The percent error is calculated as follows: | measured value accepted value | percent error = x 100% accepted value 8. Does percent error measure accuracy or precision? Explain.
