Quality measurement in research is essential. Measurement involves assigning numbers to concepts,
objects, events or situations following a set of rules derived by the researcher through instrumentation or the
use of tools for measurement. These measurements should be accurate and consistent. Chapter 16 in Gray,
Groces and Sutherland (2017) explains the way that validity and reliability can be achieved. Check out page

A researcher performs a
series of pilot studies to
evaluate whether a
measurement tool produces
consistent results.
A researcher develops a 7-
point Likert scale to
evaluate feelings of well-
being in patients who are
undergoing chemotherapy.
The researcher administers
this measure to other,
similar patients in other
medical centers.
In a research study,
ambulatory clinic nurses
teach children with asthma
how to monitor peak
expiratory flow volumes and
how to use metered-dose
inhalers to determine
whether asthma control
scores improve. The
researcher discovers
inconsistencies in how
these measures were taught
and how well the children
understood the concepts.
A researcher reviews
demographic characteristics
of potential study subjects,
such as age and gender, to
determine whether these
characteristics may
influence the outcome of the
study.
