EVIDENCE BASED PRACTICE QUIZ 3 (LATEST UPDATE)
REAL QUESTIONS AND VERIFIED ANSWERS |100%
CORRECT | ALREADY GRADED A
research design Ans✓✓✓ encompass multiple aspects of research
process - refer to a specific plan or blueprint
categories of quantitative designs Ans✓✓✓ identifies what is wrong -
includes experimental (cause and effect), nonexpiremental ( describing a
phenomenon) and quasi (mixture of both qualitative and quantitative)
key concepts and principles in quantitative design Ans✓✓✓ causality,
probability, control, manipulation, extraneous variables, bias,
randomization, between groups, within groups
causality Ans✓✓✓ cause and effect - manipulating independent variable
effects the dependent variable - the relationship between cause and
effect
control Ans✓✓✓ ability of researcher to manipulate, regulate, or
statistically adjust for factors that can affect the dependent variable or
intervention
probability Ans✓✓✓ likelihood or chance of an event to occur in a
situation
,manipulation Ans✓✓✓ ability of the researchers to control the
independent variable
bias Ans✓✓✓ want to see certain results - results may not be true -
similar to extraneous variables - encompasses extraneous variables -
when extraneous variables influence the relationship between the
independent and dependent variables
randomization Ans✓✓✓ reduces bias - the selection of assignment or
arrangements of elements by chance
translational research Ans✓✓✓ taking research and applying it right to
the bedside
double blind Ans✓✓✓ researcher and subject both do not know if they
are getting actual or placebo
random sampling Ans✓✓✓ used for a population - technique for
selecting elements whereby each has the same chance of being selected
random assignment Ans✓✓✓ chance of being in one group = chance of
being in another group - assignment technique in which subjects have an
equal chance of being in either the treatment or the control group
, between group designs Ans✓✓✓ example would be freshman vs.
sophomores - two separate groups are used - study designs when two
groups of subjects can be compared
study validity Ans✓✓✓ ability to accept results as logical, reasonable
and justifiable based on the evidence presented
within group designs Ans✓✓✓ comparisons at two or more points in
time of two or more measures - example is pre and post test -
comparisons are made about the same subjects at two or more points in
time or on two or more measures
internal validity Ans✓✓✓ the degree to which one can conclude that the
independent variable produced changes in the dependent variable
validity Ans✓✓✓ degree research can result as a intervention
threats to internal validity Ans✓✓✓ occur inside study - includes
selection bias, maturation, history, testing, instrumentation, mortality,
statistical conclusion validity
selection bias Ans✓✓✓ participant chooses what group they want to be
in- a threat to internal validity when the change in the dependent
variable is a result of the characteristics of the subjects before they
entered a study
