Measurement

Question 1 • FL-2003010-M/J Physical Science

Which statement accurately describes how scientists collect data?

Answer
A
The units used to record data are different depending on the country.
B
More complex devices are always better for collecting data.
C
The method used to collect data depends on the desired data.
D
Simple devices are always better for collecting data.

Explanation

Scientists choose a data-collection method based on what they want to measure and how precise the results need to be. For example, measuring a classroom’s length may call for a tape measure, while measuring a tiny distance may require a more precise instrument. Neither complex nor simple devices are always better, so the statement that the method depends on the desired data is accurate.
