Kemtec™ AP™ Chemistry Kits: Statistics: Precision & Accuracy

Description

Requires

Analytical balance

Use a variety of basic volumetric measuring techniques to distinguish between precision and accuracy, while identifying an unknown liquid by its density.

Lessons include statistical analysis calculations of mean, standard deviation, and relative error. Students address the Inquiry Question: How is a physical constant used to verify the precision of a measuring tool? Ideal for AP Chemistry, Chemistry I or II, or Honors Chemistry.
