Answer to Question 1

ANS: D
Demographic variables are characteristics or attributes of subjects that are collected to describe the sample.
Heart rate would not be considered a demographic variable. Demographic variables are characteristics or attributes of subjects that are collected to describe the sample.
Oral temperature would not be considered a demographic variable. Demographic variables are characteristics or attributes of subjects that are collected to describe the sample.
Pain intensity would not be considered a demographic variable. Demographic variables are characteristics or attributes of subjects that are collected to describe the sample.

Answer to Question 2

ANS: C
An operational definition is derived from a set of procedures or progressive acts that a researcher performs to receive sensory impressions that indicate the existence or degree of existence of a variable. An operational definition is developed so that a variable can be measured or manipulated in a concrete situation. In this example, pain is the sensory impression being measured on a numerical scale.
A hypothesis indicates the researcher's educated guess at what the outcome of the research will be. An associative hypothesis describes a predicted relationship that the researcher develops between the established variables being studied. This statement is an operational definition, not a hypothesis.
A conceptual definition is the theoretical meaning of a variable.
The problem statement indicates the gap in knowledge needed for practice and provides a basis for the study.
