APPLIED HEALTHCARE STATISTICS PRE-
ASSESSMENT PRACTICE SOLUTION 2026
QUESTIONS WITH ANSWERS GRADED A+
⩥Cochrane Collaboration. Answer: develop and disseminate systemic
reviews of healthcare interventions
⩥Florence Nightingale David. Answer: produced the first edition of
Tables of the Correlation Coefficient
⩥population. Answer: 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. Answer: A group selected from the population in the hope that
the smaller group will be representative of the entire population.
⩥parameter. Answer: characteristic of a population
⩥statistic. Answer: characteristic of a sample
,⩥descriptive statistic. Answer: 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. Answer: 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. Answer: 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. Answer: 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. Answer: the raw materials of research, they provide the numbers
upon which we perform statistics
⩥variables. Answer: any characteristic that can and does assume
different values for the different people, objects, or events being studied
, ⩥random assignment. Answer: Assignment of individuals to groups by
chance (ie, every subject has an equal chance of being assigned to a
particular group).
⩥independent variable. Answer: The variable that is seen as having an
effect on the dependent variable. In experimental designs, the treatment
is manipulated.
⩥dependent variabe. Answer: The variable that measures the effect of
some other variable
⩥treatment group. Answer: the group in an experimental investigation
that is subjected to the change in the independent variable
⩥control group. Answer: In an experiment, the group that is not exposed
to the treatment; contrasts with the experimental group and serves as a
comparison for evaluating the effect of the treatment.
⩥continuous variable. Answer: A variable that can take on any possible
value within a range. For example, weight is a continuous variable
because a weight of 152.5 lb makes sense.
⩥discrete variable. Answer: number of children is a discrete variable
because it can take on only certain values (0, 1, 2, and so on). A value of
1.2 for children does not make any conceptual sense.
