CORRECT ANSWERS GRADED A+/verified
Standard Deviation (SD)
Helps the researcher to compare whether two groups have
different average values. A paired ____________ is used when each
observation in one group is paired with a related observation in
another.
t-test
Is the factor that is directly manipulated by the researchers. The
dependent ________ is the measurable ________ that depends on
the independent ____________.
Variable
Used for advanced data mining. Hold huge amounts of data, used
when multiple organizations join to share information, i.e., ACO
or HIE.
Data warehouse
Data stored in various tables, each table has a key
field to connect it to other tables, making all tables related to
each other. Most common.
Relational Database
In addition to text, stores audio, video, images, other 'objects'.
Object Oriented Database
Used online for actions such as lab sending information to
clinical area. Has the capacity to roll back to originally stored
information if power outage or hacking. Most relational
databases today have this capacity.
Transactional Database
A business intelligence analyst at a regional healthcare system
is developing reports for clinical quality improvement projects
and best practice guideline development. The best practice
guidelines will be used across the entire
,regional system. Which type of database would be used to gather
and analyze data for the reports needed?
data warehouse
A hospital is onboarding a new cardiothoracic surgeon who is
moving from a different state to join their physician team. Which
data source will be used to ensure the credentials and
background of this physician?
NPDB (National Practitioner Data Bank)
You are working on a report for the quality improvement
manager to identify Hodgkin's Lymphoma rates in the state as
they compare to your rural area. Which data source would
provide valid data for your report?
Cancer Registry
Also called cross-sectional. Analyzes data
collected from a subset of patients at a specific point in time.
Prevalence Study
Forecasts outcomes, consequences, effects,
costs. Analyzes existing data to make prediction.
Predictive Study
Investigates one person, one organization, one
group in depth. Non-participant observational.
Case Study
Data gathered on same subjects over a lengthy period of time.
Longtitudinal Study
A QI Team gathered data on all of the organization's patients with
Medicare, who received total hip arthroscopy in 2017. They will
survey these patients to determine the effectiveness of the
surgery on quality of life and functional abilities. What type of
study is this?
Prevalence Study
Draws conclusions about a larger population based on data from
a sample.
Inferential Statistics
, 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?
Descriptive Statistics
The value is in the name or label. Types of cancers (breast, skin,
lung, etc.)
Categorical Variables
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.
Confounding Variable
Also known as an interval variable. There is a meaningful
difference between values. An example is body temperature.
Continuous variable
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.
Dichotomous variable
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.
Ordinal variable
