Question

what is meant by the phrase \a consistent method of measurement\?
a. things are measured the same way each time.
b. every measurement is exactly the same numerical value.
c. all measurements are in si units.
d. the same person performs all measurements

Explanation:

A consistent method of measurement means that the same procedure is followed each time a measurement is taken. This ensures reliability. Option A correctly captures this idea. Option B is incorrect as measurements can vary (due to experimental error etc. even with a consistent method). Option C is about units (not the method). Option D is about who performs the measurement (not the method's consistency).

Answer:

A. Things are measured the same way each time.
