Applied Healthcare Statistics COMPLETE EXAM
Questions And CORRECT Answers
US Preventative Services Task Force - CORRECT ANSWERS develop evidence-based
guidelines for healthcare
Cochrane Collaboration - CORRECT ANSWERS develop and disseminate systemic reviews
of healthcare interventions
Florence Nightingale David - CORRECT ANSWERS produced the first edition of Tables of
the Correlation Coefficient
population - CORRECT ANSWERS The entire group having some characteristic (eg, all
people with depression, all residents of the United States). Often a sample is taken of the
population and then the results are generalized to that population.
sample - CORRECT ANSWERS A group selected from the population in the hope that the
smaller group will be representative of the entire population.
parameter - CORRECT ANSWERS characteristic of a population
statistic - CORRECT ANSWERS characteristic of a sample
descriptive statistic - CORRECT ANSWERS numerical or graphical summaries of data, and
may include charts, graphs, and simple summary statistics such as means and standard
deviations to describe characteristics of a population sample
, inferential statistics - CORRECT ANSWERS statistical techniques (e.g., chi-square test, the t
test, the one-way ANOVA) that allow conclusions to be drawn about the relationships found
among different variables in a population sample
quantitative variables - CORRECT ANSWERS a characteristic that can be measured
numerically, a characteristic with numeric values that have meaning and for which arithmetic
operations such as adding and averaging make sense. Ex: height, weight, income, heart rate, etc.
categorical variables - CORRECT ANSWERS a characteristic that takes on values that are
names or labels.These are data that cannot be averaged or represented by a scatter plot as they
have no numerical meaning. Ex: The color of a ball, gender, year in school.
data - CORRECT ANSWERS the raw materials of research, they provide the numbers upon
which we perform statistics
variables - CORRECT ANSWERS any characteristic that can and does assume different
values for the different people, objects, or events being studied
random assignment - CORRECT ANSWERS Assignment of individuals to groups by chance
(ie, every subject has an equal chance of being assigned to a particular group).
independent variable - CORRECT ANSWERS The variable that is seen as having an effect
on the dependent variable. In experimental designs, the treatment is manipulated.
dependent variabe - CORRECT ANSWERS The variable that measures the effect of some
other variable
treatment group - CORRECT ANSWERS the group in an experimental investigation that is
subjected to the change in the independent variable
