QUESTIONS AND VERIFIED
CORRECT ANSWERS GRADED A+
LATEST 100% GUARANTEED PASS
Clinical trial - CORRECT ANSWER-A research study in which a drug, intervention or device is
studied to evaluate the efficacy and safety of treating a specific problem or disease; to find
superior or alternative modalities of treating a specific disease
randomized control trial - CORRECT ANSWER-gold standard and most commonly used method;
involves identification of population of interest, selecting a sample population from that group
and typically sample population broken into two or more groups
Validity - CORRECT ANSWER-Degree with which correct inferences can be made from the results
of a research study
internal validity - CORRECT ANSWER-Extent to which results obtained in a research trial are a
function of the variables that were systematically manipulated, measured, and/or observed in
the study
Bias - CORRECT ANSWER-Systematic error; occurs when the way a study was designed,
conducted or recorded leads to systematic deviations from results of the truth
, random error - CORRECT ANSWER-an error that occurs when the selected sample is an
imperfect representation of the overall population; chance error or statistical error; occurs due
to variability in measured data that arrives purely by chance
Selection bias - CORRECT ANSWER-Randomization is the process of assigning study participants
to either experimental or control groups at random to prevent this
Randomization - CORRECT ANSWER-Allocation sequence generation; allocation concealment;
implementation of allocated sequence
allocation sequence generation - CORRECT ANSWER-Generating unpredictable sequence of how
subjects are allocated; random numbers or computer generated random number system
allocation concealment - CORRECT ANSWER-Generates random sequence of allocation that
prevents participants and researchers alike from knowing which group the subject was assigned
allocated sequence implementation - CORRECT ANSWER-Once treatment assignment is made
for a particular patient, it is enforced
confounding - CORRECT ANSWER-occurs when two variables are associated in such a way that
their effects on a response variable cannot be distinguished from each other; mix up
(something) with something else so that the individual elements become difficult to distinguish
performance bias - CORRECT ANSWER-Bias that occurs due to systematic differences in care
between treatment groups or in exposure to factors other than the intervention being studied
(bias introduced by the care provided)
detection bias - CORRECT ANSWER-awareness of progress in outcome assessment (subject
believes they are getting a treatment and expects improvement)
