Question 1 pts
A researcher studies the effect upon dental caries formation of a year-long
regimen of daily rinsing with a particularly noxious-flavored oral solution,
only to discover than 285 of the 300 subjects in the study have withdrawn

, from it by the end of the first month. Which step in the research process
was not properly undertaken?
Selecting study variables
Correct! Performing a pilot study
Conducting the literature review
Defining the purpose
A pilot study is commonly defined as a smaller version of a proposed
study conducted to refine the methodology. It is developed much like
the proposed study, using similar subjects, the same setting, the
same treatment, and the same data collection and analysis
techniques. Some of the reasons for conducting pilot studies are to
determine feasibility, to develop a treatment or intervention, to
develop an implementation protocol, to identify problems with the
design, to evaluate the sampling method, to examine instrument
reliability or validity, to refine instruments, to refine plans for data
collection and analysis, to provide research experience, and to
evaluate data analysis techniques.
Question 2 pts
What does a quantitative research instrument measure?
The level of measurement
A statistical test
Itself, for validity
Correct! A study variable
When conducting a quantitative study, the researcher attempts to use the most
precise instruments available to measure the study variables.

, Question 3 pts
A research study contains the following in its Introduction section: “This
study was undertaken to explore the effect of massage on total hours of
sleep per 24-hour day, in persons averaging fewer than 7 hours of sleep per
night, attributable to insomnia. . . . Presumably by increasing endorphin
levels, massage seems to provide an immediate relaxation and an ability to
sleep immediately following the session, but it is unclear whether these
benefits actually extend to total sleep, despite anecdotal support. The claim
that massage increases total hours of sleep has been inadequately
researched. . . . Does massage increase the total number of hours of daily
sleep? . . . It was posited that provision of daily late-morning massage would
affect total hours of sleep per 24-hour day. The study’s causational
explanation was based on the physiologic matrix of McCarthy, which
includes effects of endorphins on sleep, learning ability, pain, digestive
function, and cardiac output. . . . It was taken as established fact that
massage is pleasant, that research subjects getting fewer than 7 hours of
sleep per night were sleep-deprived, and that endorphins mediated the
changes observed.”
