Healthcare Statistics Domain III-
Graded A
Nominal level data - ANS-Falls into groups and categories and measures data by name
only
Ordinal level data - ANS-Has an inherent order of numbers that is meaningful such as
stages of cancer
Ratio level data - ANS-Is the highest level of measurement used to calculate (los) length
of stay and has a true zero point
Discrete and Continuous data - ANS-Are ways to classify data
Discrete Variables - ANS-Ordinal and nominal data are considered to be discrete. There
are gaps between successive values
Continuous Variables - ANS-Has no gaps in measurement data and are either interval
or ratio level
Calculating a risk for contracting a disease - ANS-number of cases occurring during a
given time period/number of cases or population at risk during the same time period
Scales of Measurement - ANS-Nominal, ordinal and ratio level data
Consultation rate formula - ANS-number of consults times 100/ total discharges
FOCUS-PDCA - ANS-Is a (CQI) continuous quality improvement model that uses plan,
do, check, act process for trial , measurement, and learning
Scatter Diagram - ANS-Is a continuous quality improvement tool used to display data of
2 variables suspected to be related such as blood pressure and weight
Calculating a facility based rate - ANS-ex: 32 ekgs performed multiplied by 100/ total
number of EKG
Basic Interoperability - ANS-Can perform data exchange but no interpretation
, Semantic Interoperability - ANS-Has the highest level of interoperability
Ordinal data type - ANS-Values or observations are ranked or put in order ex: ranking in
a pain scale
Online analytical processing OLAP - ANS-A query generator that retrieves information
from a warehouse to accommodate what if queries
Interval data type - ANS-Occurs on an evenly distributed scale ex: interval between 5-
10 is the same as 10-15
Categorical data type - ANS-Values or observations are categorized ex: gender is a
category
Nominal data type - ANS-Data isn't ranked or named or measured. It's codes ex:
male=1 , female=2
ONC - ANS-Promotes an interoperative HIT infrastructure nation-wide to improve
healthcare quality and delivery
Process Interoperability - ANS-Enables businesses housing system A and B to work
together. It maintains user roles between systems
Discrete data type - ANS-Is data that has separate and distinct values
Online transaction processing - ANS-Online or real-time transaction processing that
performs intricate data searches and retrievals that link an organization physical
repository
Enterprise Report Management (ERM) - ANS-Allows organizations to get as much
information online as possible and captures images and documents that are stand-
alone electronic systems and make them availible for viewing on a monitor
ERM - ANS-Electronic or enterprise report management
Continuous data type - ANS-Is metric data. Think of a ruler. ex: number points are
indefinite and continuous along a continuum
Systemic sampling survey - ANS-A random sampling such as every 5th member
Convenience sampling survey - ANS-Uses any subject available
Stratified sampling survey - ANS-Subjects are divided into subgroups and you choose
which group to survey
Cluster sampling survey - ANS-clusters subjects by common characteristics
