APPLIED HEALTHCARE STATISTICS EXAM
PRACTICE QUESTIONS AND 100%
CORRECT ANSWERS!!
The fact that we can add the same number to both sides of an equation, and the result will
be an equivalent equation.
addition principle of equality
Used to determine the probability that at least one of two events will occur.
P(A or B) = P(A) + P(B) - P(AB)
Addition Rule of Probability
Two integers that are opposites. The sum of an integer and its additive inverse is zero. (-3,
0, and 3)
additive inverse
A pattern or relationship between two variables.
association
A graph that displays data that is distributed over groups or categories.
bar chart
a data set which has two modes/peaks in the graph
bimodal
A graph that displays the highest and lowest quarters of data on each end of the box, the
middle two quarters of the data as a box, and the median
box plot
Also called Qualitative data. Data that consists of names, labels, or other nonnumerical
values
, categorical data
a relationship between two variables: cause and effect
casual relationship
a number multiplied by a variable.
coefficient
when you simplify an algebraic expression
combining like terms
A number with more than two factors
composite number
a way to approximate percentage by dividing the number of times an event occurred in an
experiment by the total number of experiments/ relative frequency
conditional percentage
A contingency table displays counts and, sometimes, percentages of individuals falling into
named categories on two or more variables.
contingency table
an observed relationship between two quantitative variables.
correlation
the sum of probabilities. the chance that a randomly selected score will be less than or
equal to a specified value.
Cumulative Property
n-1 (any # minus 1)
degrees of freedom
Two or more events in which the outcome of one event affects the outcome of the other
event(s).
