UPDATED QUESTIONS AND ANSWERS
GRADED A+
⩥ When should the selection of data-collection methods occur?
A. During the literature review
B. From data collection
C. In sample selection
D. During the review of protection of human subjects. Answer: A
During the review of literature, the researcher begins to explore how
previous investigators defined and operationalized variables similar to
those of interest in the current study. Selection of data-collection
methods must occur well before data collection. Selection of data-
collection methods must occur well before sample selection. Selection of
data-collection methods must occur well before review of protection of
human subjects.
,⩥ How can consistency in data collection be ensured?
A. By using physiological data-collection methods
B. By having one person collect the data
C. By avoiding the use of observation methods
D. By collecting data from each subject in the same way. Answer: D
Consistency refers to the collection of data in the same way by all data
collectors throughout the study. Data-collection methods can be
consistent without the use of physiological methods. Multiple people can
collect data as long as safeguards are in place to ensure consistency.
Observation methods can be collected consistently as long as those
collecting the data are trained and monitored throughout the process.
⩥ The degree of consistency in data collection between two
investigators is referred to as what?
A. Interrater reliability
B. Reactivity
C. Debriefing
, D. Cross-rater validity. Answer: A
The degree to which two investigators collect data consistently is
referred to as interrater reliability. Reactivity refers to the change in
behavior of a subject as a result of being involved in a study. Debriefing
refers to informing subjects after the fact that they have been observed
and allowing them to refuse to have the observation included as part of
the research study. Cross-rater validity refers to the measurement of the
same dependent variables by all data collectors.
⩥ An example of a biological measurement would be what?
A. Pain rated on a scale of 1 to 10
B. A blood glucose level of 110 mg/100 mL
C. Pitting edema in both ankles
D. Blue-tinged lips and nail beds. Answer: B
Biological measurement involves the use of specialized equipment to
determine physical and biological characteristics of subjects. Pitting
edema and color of lips and nail beds are assessed without such
equipment. Pain is a psychological measurement.
