1. The researchers recruited 80 physicians (44 men and 36 women) and 113
nurses (10 men and 103 women) for a total sample of 193. Approximately
71% of participants were female, 69% were Caucasian, 11% were African
American, 6% were Hispanic, 10% were Asian, and 4% identified as Other.
The average age of the healthcare providers was 44 years (range: 22-75),
and the average years of professional experience was 15 years (range: 1-
47). A majority of the healthcare professionals lived in Florida (N = 148).
This is an example of what type of statistics?
- ANSWER Descriptive Statistics
2. The value is in the name or label. Types of cancers (breast, skin, lung, etc.)
- ANSWER Categorical Variables
3. It obscures the effect of another variable, the researcher may initially
believe the variable will have an influence on the research, but findings
show it does not. As a researcher, you may not be able to control its
influence on the result of the research, but you should have an awareness
that it is impacting your results and do not allow it to skew your data.
- ANSWER Confounding Variable
4. Also known as an interval variable. There is a meaningful difference
between values. An example is body temperature.
, - ANSWER Continuous variable
5. Also called a binary variable. Occurs in one of two possible states. For
example, male or female. The patient has cancer or does not have cancer.
- ANSWER Dichotomous variable
6. Order matters, but not the difference between the values. Example: Likert
Scale, which is subjective. Another example is birth order. Children are
ranked according to the order in which they are born, but years between
each child may vary.
- ANSWER Ordinal variable
7. Single table database. Cannot merge, must cut and paste. Good for storage
of information. Similar to Excel spreadsheet.
- ANSWER Flat File database
8. Older type of database. Structured like an organizational chart, has a one to
many relationship. Slow response time to retrieve data due to the way
relationships are built into the database.
- ANSWER Hierarchical database
9. Have the capability to process large amounts of data quickly. Used for ad-
hoc situations: info needed now. Stored, viewed, and analyzed from
different perspectives: these perspectives are called dimensions.
- ANSWER Multidimensional database
10.All patient information removed, cannot identify patient through any data
point. Used in clinical trials for anonymity/ protection of human subjects, to
encourage valid research.
- ANSWER De-identified database:
,11.The manager of Imaging Services receives a call from the COO: the CEO is
requesting comparison data on the volume of imaging services from each of
the five regional hospitals in the network, from the past quarter. The report
is due in one hour. Which database will be useful in gathering the data for
this report?
- ANSWER Multidimensional database
12.An agency of the U.S. Department of Health and Human Services. Primary
federal agency for improving healthcare to people geographically isolated,
economically or medically vulnerable.
- ANSWER Health Resources and Services Administration (HRSA)
13.Physicians in a northwest coast metropolitan city are concerned about the
medical needs of the growing homeless population living in their streets.
Which of these would be a good source of information and assistance in
planning programs to serve this population?
- ANSWER Health Resources and Services Administration (HRSA)
14.Incorrect application of a statistical test can result in a type I _________,
which occurs when a null hypothesis is rejected when it should have been
accepted. A type II ________ is experienced when the alternative
hypothesis is rejected when it should have been accepted.
- ANSWER Error
15.In research, this principle is the right for a person to participate as a human
subject, or not. In healthcare, it refers to a patient having the right to make
their own choices, unless they have been legally deemed unable to do so.
- ANSWER Autonomy
16.Is a concept which concerns the welfare of a research participant, but can
also apply to treatment of patients. The opposite term, "maleficence"
, describes opposing the welfare of a research participant. You may also see a
term, "malfeasance" which is intentional conduct outside the law.
- ANSWER Beneficence
17.This principle requires loyalty, fairness, truthfulness, advocacy, and
dedication to patients (and others). It involves an agreement to keep
promises, to keep a commitment, and is based on the virtue of caring. This
principle would include patient advocacy.
- ANSWER Fidelity
18.Is the process of predicting outcomes and needs to create systems and
models with the highest financial and operational safety and efficiency; it
can be used to determine potential use of services and patient demand, or
to expand service lines and markets.
- ANSWER Forecasting
19.Defined as "differences in the incidence, prevalence, mortality, and burden
of diseases"; frequently seen in subpopulations based on socioeconomic
status, geography, race, ethnicity, sexual orientation, or special needs.
- ANSWER Health disparities
20.In research, it pertains to the fair selection of research participants. This is
the ideal distribution of risks and benefits when conducting clinical research
and recruiting volunteer research participants to participate in clinical trials.
One example that we see in the U.S. of the principle of justice is that in our
country, when a citizen turns 65 years of age, he or she is eligible for
Medicare, no matter who they are or their socioeconomic level.
- ANSWER Justice
21.The purpose of _______________ is to determine the relationship between

- ANSWER Multiple regression
