Once the lab exam begins, you are not permitted to receive any assistance from your TA or other students. [2] [3] Although the two words precision and accuracy can be synonymous in colloquial use, they are deliberately contrasted in the context of the scientific method . Precision and Uncertainties for Common Lab Equipment When you record a scientific measurement, the last digit that you record is understood to have some uncertainty, and to be your best estimate. YOU WILL BE PENALIZED IF YOU RECORD YOUR DATA ANYWHERE BUT YOUR LAB NOTEBOOK. However, you may use your lab manual, graded lab reports, notes, and textbook as resources for this exam.
