(Western Governors University) – Objective
Assessment Study Material and Practice Q&A
Introduction:
This document provides a comprehensive collection of key
definitions, formulas, and solved practice questions aligned
with the WGU C784 Applied Healthcare Statistics Objective
Assessment. It covers foundational math concepts, statistical
terminology, probability principles, graph types, and
regression basics. The material includes worked examples,
multiple-choice questions with answers, and concise
explanations to support exam preparation. It is well-suited for
students seeking a complete and streamlined study resource.
Exam Questions and Answers:
What is the greatest common factor of 24 and 84 using prime
factorization?
A. 2
B. 4
C. 8
D. 12 -Answer:-D. 12
,Negative Number -Answer:-A number whose value is less than
zero. On the number line, negative numbers are to the left of
zero.
Numerator -Answer:-The number that is written before the
slash, or above the fraction bar, in a fraction.
Slope -Answer:-The number that describes the direction and
steepness of a line drawn on the coordinate plane. It is
measured by 'rise over run'. Rise/Run = (the change in y
value) / (the change in x value) = (y2-y1)/(x2-x1).
Statistics -Answer:-The science that deals with the
interpretation of numerical facts or data through theories of
probability. Also, the numerical facts or data themselves.
Conditional Percentages -Answer:-A way to approximate a
percentage by dividing the number of times an event occurred
in an experiment by the total number of respondents in that
row or column. See Relative Frequency.
Hypothesis Test -Answer:-A statistical test that tells us
whether a result is significant.
, Disjoint -Answer:-Two events which both cannot occur at the
same time.
What is 3/14 - 1/7?
A. 1/14
B. 2/7
C. 5/14
D. 3/2 -Answer:-A. 1/14
Whole Number -Answer:-A number whose value is 0 or greater
(negative number are not considered whole numbers) and can
be represented without a fractional or decimal component.
Cross Multiplying -Answer:-A method used to prove that a
proportion is true.
Addition Principle of Equality -Answer:-The fact that we can
add the same number to both sides of an equation, and the
result will be an equivalent equation.
