Data Analysis
Section 2.1 Units of Measure1. Define SI base units for time, length, mass, and temperature. 2. Explain how adding a prefix changes a unit. 3. Compare the derived units for volume and density.
Section 2.2 Scientific Notation and Dimensional Analysis 1. Express numbers in scientific notation. 2. Use dimensional analysis to convert different units of measure.
Section 2.3 How reliable are measurements? 1. Define and compare accuracy and precision. 2. Use significant figures and rounding to reflect the certainty of data. 3. Use percent error to describe the accuracy of experimental data.
