Chapter 2, Problem 7a
On a typical day, medical personnel may encounter several situations involving measurement. State the name and type of measurement indicated by the units in each of the following:
a. The clotting time for a blood sample is 12 s.
Verified step by step guidance1
Identify the unit provided in the problem. In this case, the unit is 's', which stands for seconds.
Determine what the unit 'seconds' measures. Seconds are a unit of time in the International System of Units (SI).
Understand the context of the problem. The clotting time refers to the duration it takes for a blood sample to clot, which is a time-based measurement.
State the name of the measurement. The name of the measurement is 'clotting time'.
Classify the type of measurement. Since the unit is seconds, the type of measurement is 'time'.
