Significant Digits and rules for rounding
Significant Digits and Accuracy
Overview
This module is an introduction to Accuracy, Precision, and Sig figs. It includes how to count the number of significant digits and defining accuracy versus precision.
How important are the numbers?
With an experimental science like chemistry, the numbers we record from our experiments are of paramount importance! If our data are not accurate, we cannot draw any conclusions and we've just wasted your hard-earned taxpayer dollars (if in an academic or government lab).
These videos explain why Significant Digits (sig figs) has meaning in any experimental field, defines accuracy and precision, and demonstrates how to count sig figs.
