9/1/20 REPORT Experiment 1 Measurement and Error Analysis Student Name Section Number: Instructions 1) Follow all of the lab activity steps given in the Lab Procedure. 23 Attach your completed data tables to this page. 3) 4) TYPE YOUR ANSWERS IN THE PROVIDED SPACES below & in your data tables Altach additional sheets of paper that clearly (NEATLY) show all of your calculations performed during this experiment Results 1) What sources of systematic error might be present in your experimental data? What effect would these error sources have on your data? Write out your answer in a clear and well supported paragraph. erase this and type in your answer 2) For each of the objects you measured, does the precent error between your calculated density and the actual density represent primarily measurement error, or is there significant systematic error in your data? Explain how you make this determination. Write out your answer in a clear and well supported paragraph. % UNCERTAINTY in DENSITY (Ad/ D) X 100 %. Calculate percent uncertainty in Density for each case A,B,C and compare the percent uncertainty with percent error for that metal if % ERROR=[lexptal value - Accepted valuel/ Accepted value] x 100% % ERROR <% UNCERTAINTY then it is a MEASUREMENT ERROR I % ERROR > % UNCERTAINTY then It is a SYSTEMATIC ERROR 3) Describe how the error in this experiment might be reduced. Write out your answer in a clear and well supported paragraph. erase this and type in your answer
