Propagation of uncertainty

Error and Propagation of Error

Students will learn to: Differentiate between accuracy and precision. Describe two main types of error in chemical analysis. Express experimental error as either absolute or relative uncertainty. Use the real rule of significant figures when expressing values that have an associated uncertainty.

Propagation of Uncertainty and Titrations

Students will learn to: Determine an unknown quantity using titration data. Propagate uncertainty for common mathematical operations including: Addition/subtractions Multiplication/division Perform the appropriate propagation of uncertainty in the context of volumetric chemical analysis. Use error analysis to determine the least accurate part of an analytical procedure.
