Significant Figures

Significant figures—also called significant digits—are used in chemistry, physics, and in any physical science class to represent measured data accurately. Read this e-book and all your problems with representing your work accurately in lab reports or on-the-job reports will forever vanish.
Significant figures are not a nostrum for measured data error analysis; they are a bridge to the fascinating field of error analysis. Significant digits are used in high school, college, and even in the real world—your job.
The problem or predicament people face with their introduction to significant figures is not only working with measured data accurately but also the professor is keeping score. From the first lab report, points are taken away from your grade for not representing data accurately. Read this e-book and save your grades or your job.
Graduate school admission teams and future employers know nothing about you. The only way for them to judge you accurately is your grades. Do not lose points unnecessarily that you need to succeed.
