NURS 328 - Quiz 2
hypotheses used when conducting experimental or quasi experimental research in the
quantitative paradigm.
A hypothesis Consists of an independent variable and a dependent variable; these
variables are described in relation to each another.
Experimental In a(n) ___________ design the researcher controls (manipulates) the independent
variable and randomly assigns subjects to different conditions.
pre-experimental A(n) __________design does not include mechanisms to compensate for the
absence of either randomization or control group
quasi-experimental In a(n) _______ design the investigator does not randomly assign participants
but does manipulate the independent variable and controls to enhance the
internal validity.
,NURS 328 - Quiz 2
non-experimental In a(n) ___________ design the researcher collects data without introducing any
treatment.
5. This experimental design is sometimes called a crossover design. In the
repeated measure design one group of subjects is exposed to more than
one condition in random order.
repeated measure This experimental design is sometimes called a crossover design. In the
________________design one group of subjects is exposed to more than one
condition in random order.
non-equivalent This is a type of quasi-experimental design that involves a comparison group
that was not developed on the basis of random assignment. It is called a
_______________ control group design.
retrospective study A(n) ________________ begins with the occurrence of the dependent variable in the
present and then links this effect to some presumed cause which occurred in
the past.
dependent variable The outcome factor; the variable that may change in response to
manipulations of the independent variable.
experimental study the researcher manipulates one of the variables and tries to determine how
the manipulation influences other variables
,NURS 328 - Quiz 2
hypthesis explanation of observations that are testable through experimentation or
observation, educated guess
independent variable The experimental factor that is manipulated; the variable whose effect is
being studied.
Non-experimental Without the use of a comparison or control group, has little control over the
factors that affect the validity of the results.
quasi-experimental design An experiment that does not require random assignment to conditions.
Hypotheses statements about a relationship between two or more variables
Independent variable Also known as the treatment
the variable that is manipulated
, NURS 328 - Quiz 2
Dependent variable Is the outcome
is caused by the independent variable
Research studies in the quantitative paradigm Three main types:
Experimental, quasi experimental, nonexperimental
in an experimental design The researcher manipulates the independent variable or introduces an
intervention
Subjects are randomly assigned to a treatment or a control group
(Randomized controlled trial)
(May be used to test a new drug)
