WGU C784 - Applied Healthcare Statistics Objective Assessment #1 with accurate
questions and answers
Given the following set of numbers: 3.3, -2.3, -16, 25. What are the square roots of the
whole number?
A. +/- 2.3
B. +/- 3.3
C. +/- 4
D. +/- 5 - correct answer-D. +/- 5
Composite Number - correct answer-A number with more factors that just one and itself.
Equivalent Fractions - correct answer-Different fractions that represent the same value.
X-Axis - correct answer-The horizontal line that passes through the origin on a coordinate
plane.
Qualitative Data - correct answer-Non-numeric information based on some quality or
characteristic.
No Correlation - correct answer-There is no apparent overall trend between the two
variables. If the correlation coefficient is 0, this only rules out a linear trend. There could be
a non-linear or curvilinear trend.
Extrapolate - correct answer-Using information from a data set to make predictions about
data outside of the original set.
Event - correct answer-An outcome, or set of outcomes, whose chance of occurrence can
be represented with a probability.
Given the following set of numbers: 10, 2.5, -4, -4.5, 5. What is the sum when adding
together only the whole numbers?
A. 5.5
B. 11
C. 12.5
D. 15 - correct answer-D. 15
Operation - correct answer-In Mathematics, an operation is a procedure which generates a
new value from one or more operands, or Mathematical values.
, Conditional Proportion - correct answer-A proportion where one part of the proportion is a
variable, or unknown quantity.
Coefficients - correct answer-A number by which a number is multiplied. This number is
written in front of the variable(s).
Mean - correct answer-Average, calculated by adding a series of elements in a data set
together and dividing by the total number in the series.
Outlier - correct answer-An observation point that is statistically distant from the other
observations in the dataset.
Regression Line - correct answer-The line of best fit to show the relationship between
variables, the one that minimizes distance from each data point to the line.
Experiment - correct answer-A procedure that can be done repeatedly which has a well
defined set of outcomes.
Given the following expression: 4 + 7 × (6 - 3)2. What is the answer using proper order of
operations?
A. 25
B. 46
C. 67
D. 99 - correct answer-C. 67
Multi-Step Expression - correct answer-An expression or equation with more than two
values and two or more operators that requires multiple steps to be solved.
Improper Fraction - correct answer-A fraction where the number in the numerator is more
than the number in the denominator.
Y-Intercept - correct answer-The y-value of the point at which a line intersects with the y-
axis.
Check Sheet - correct answer-A structured form or table that allows data to be collected
by marking how often an event has occurred in an certain interval.
Linear - correct answer-An expression or equation of degree 1.
Least Squares - correct answer-A technique for finding the regression line.
Sample Size - correct answer-The number of different outcomes for an experiment.
