LAB 2.2 Measure for Measure Quiz

What is the purpose of this lab?

• To determine the best unit of measurement for length and area

• To design an experiment to evaluate two units of measurement

• To measure the length and width of objects around the room

• To calculate the area of the textbook front cover

What is a base unit of measurement?

• A unit made from a combination of base units

• A derived unit

• A fundamental unit in a measurement system

• A unit that gives precise and accurate information

What is the difference between precision and accuracy?

• Precision refers to how close together multiple measurements are, while accuracy refers to how close a measurement is to its actual value

• Precision refers to how close a measurement is to its actual value, while accuracy refers to how close together multiple measurements are

• Precision and accuracy are the same thing

• Neither precision nor accuracy are important in measurements
