MULTIPLE CHOICE

 

1. A researcher conducts a study to examine the effects of breastfeeding on infant weight at age 6 months. Which type of measurement is used to measure the infants’ weight?

a.	Direct
b.	Indirect
c.	Nominal
d.	Ordinal

 

 

ANS:  A

 

	Feedback
A	Direct measurement allows for measures of concrete factors, such as a person’s height or weight.
B	Indirect measurement measures abstract ideas or characteristics and often must use more than one measure to measure all aspects of the concept.
C	Nominal level measurement is used when data can be organized into categories of a defined property, such as a disease diagnosis, but when categories cannot be rank ordered.
D	Ordinal level measurement is used when data collected can be rank ordered.

ANS:  B

 

	Feedback

3. A researcher conducts a study to identify the relationship of lifestyle choices to the development of chronic diseases. The researcher surveys subjects and identifies diabetes mellitus, coronary artery disease, and renal disease in study subjects. These measures represent which level of measurement?

a.	Interval
b.	Nominal
c.	Ordinal
d.	Ratio

 

 

ANS:  B

 

	Feedback
A	Interval level measurement uses interval scales, which have equal numerical distances between intervals.
B	Nominal level measurement is used when data can be organized into categories of a defined property, such as a disease diagnosis, but when categories cannot be rank ordered.
C	Ordinal level measurement is used when data collected can be rank ordered.
D	Ratio level measurement uses all aspects of other types of measurement: mutually exclusive categories, exhaustive categories, ordered ranks, equally spaced intervals, and a continuum of values.
