Question

Directions: Write the value and uncertainty in the proper “presentation format”. (1) Round off uncertainty to two (2) significant figures (2) Round off value to same decimal place as last significant digit in uncertainty (3) When using scientific notation, make sure value and uncertainty are expressed to same power of ten, with decimal point placed after first digit in the value. Example: (5.423 ± 0.034) x 10-5 (4) Hint: If your value is greater than 10,000 or less than 0.01 you must use scientific notation. Note on Grading: This sheet must be done perfectly to receive an 8/10. If this second version is not done perfectly, then you will be given a new version, and if that one is completed perfectly then you will receive a 7/10. You will continue to lose points until this sheet is completed perfectly. See lab manual for details on presentation format.
