Distinguish accuracy, precision, reliability, and validity by defining them all correctly.
Accuracy - how close the measurement gets to the correct result
Precision - how consistently the same result is measured with the same measurement tool
Reliability - yielding the same results when the experiment is repeated
Validity - whether or not the experiment measures what it truly aims to measure

Complete the following metric conversion: A cell phone company wants to build a new tower, but it will need to figure out the maximum distance the tower can be from the city in order to provide adequate service. The signal can reach 27.89 km. The company is planning on placing the tower 2.5 million centimeters away from the city. Will this distance suffice?
Yes, it must be at most 2,789,000 centimeters away.

Mr. Weinhold wants to collect data on student culture at NPX. More specifically, he wants to see how clear classroom protocols affect student behavior. He chooses five teachers with clear protocols and five teachers with unclear protocols, and surveys their students. The students rate the effectiveness of each teacher’s classroom protocols. Then Mr. Weinhold observes each teacher’s class and collects data on student behavior.
What is the independent variable in this experiment? What is the dependent variable in this experiment? What is the control for this experiment? Which scale of measurement is being used for this experiment?
Independent - use of clear classroom protocols
Dependent - student behavior
Control - teachers’ classes without clear classroom protocols
Ordinal - student surveys
