Applied Healthcare Statistics – C784 (WGU) –
2024–2025 – Complete Objective Assessment
Study Guide and Practice Answers
Introduction:
This document provides a full study guide for the WGU course
Applied Healthcare Statistics (C784), covering all major
concepts required for the Objective Assessment. It includes
definitions, formulas, worked examples, conversion tables,
probability rules, data types, graphical displays, and set theory
fundamentals. The material is structured as a comprehensive
reference to support exam preparation and mastery of core
statistical competencies.
Exam Questions and Answers:
41. emperature is an example of continuous data. True or
False?-Answer:- This statement is true. Temperature covers an
entire interval of data and can be "measured" rather than
counted, so it is continuous.
42. Timesheets log the days that a nurse works each week.
Does the week's timesheet give data that is discrete or
continuous?-Answer:- Discrete. The days of the week are
discrete and do not allow for values between them.
43. A graph shows the efficacy of a particular drug at
different dosages. Is this data discrete or continuous?-
,Answer:- Discrete. The graph shows discrete drug dosages, not
all possible dosages, between two numbers.
44. During a physical, the nurse records the patient's age,
weight, and height. Are these data discrete or continuous?-
Answer:- Continuous. These are all continuous measurements
for which it is possible to have fractional parts.
45. <-Answer:- "less than"
46. >-Answer:- "greater than"
47. -Answer:-dless than or equal to
48. -Answer:-egreater than or equal to
49. Which of the following is the correct translation of
−3<y<4-3<y<4?-Answer:- −3-3 is less than y which is less than
4 (Both of the << symbols mean "less than," so the correct
translation is −3-3 is less than y which is less than 4.)
50. How would "w is less than or equal to 9, but greater than
or equal to 5" be written?-Answer:- 9we5e(The answer is b.
Both esyembols mean "greater than or equal to," so
9we5e9we5emeans "ww is less than or equal to 99, but
greater than or equal to 55.)
51. In math, you may be asked to "evaluate an expression."--
what does that mean?-Answer:- solve the problem
52. When multiplying a positive number by a negative
number, the product will always be-Answer:- NEGATIVE
, 53. Multiplying a negative number by a negative number
results in a-Answer:- Positive product (The product of two
negatives will always equal a positive.)
54. The result of the division of two negative numbers is
always-Answer:- POSITIVE
55. Zero in multiplication =-Answer:- The product* of
multiplication with zero will always equal zero; whether
multiplying by a positive or a negative, any integer multiplied
by zero will result in zero as the product.
56. 8(superscript 0)-Answer:- Any non-zero number with an
exponent of 0 (or raised to the zero po
57. sampling-Answer:- The process of selecting research
participants from a population
58. exponent-Answer:- sometimes call a power, it is a
number that shows how many times the baseline n by itself
59. probability-Answer:- the likelihood, or chance, that a
certain event will occur
60. Order of operations-Answer:- A set of rules that tells the
order in which to compute.
61. Mode = (mode rhymes with most)-Answer:- Most often
(greatest frequency)
62. Median = middle-Answer:- Median = middle
