HCM 401 STATISTICS EXAM QUESTIONS AND ANSWERS
WITH COMPLETE SOLUTIONS VERIFIED
Auditing
The performance of internal and external reviews (audits) to identifying variations from
established baselines (ex: review of outpatient coding as compared with CMS outpatient
coding guidelines).
Centers for Medicare and Medicaid Services (CMS)
The Centers for Medicare & Medicaid Services (CMS) is part of the U.S. Department of
Health and Human Services. CMS oversees many federal healthcare programs,
including those that involve health information technology such as the meaningful use
incentive program for electronic health records (EHR).
Confidence interval
In statistics, a confidence interval (CI) is a type of interval estimate of a population
parameter. It is an observed interval (i.e., it is calculated from the observations), in
principle different from sample to sample, that potentially includes the unobservable true
parameter of interest.
Data
Facts and statistics collected together for reference or analysis.
Data Analysis
The task of transforming, summarizing, or modeling data to allow the user to make
meaningful conclusions.
, Data mining
the process of collecting, searching through, and analyzing a large amount of data in a
database, as to discover patterns or relationships
Descriptive statistics
Mathematical quantities (such as mean, median, standard deviation) that summarize
and interpret some of the properties of a set of data (sample) but do not infer the
properties of the population from which the sample was drawn.
Distribution
The pattern of values for a variable. The distribution may be characterized by center
and spread or frequency of values.
Exploratory data analysis
An approach to analyzing data sets to summarize their main characteristics, often with
visual methods.
Hospital Compare
A CMS-maintained website that reports the values of the quality indicators required for
providers to participate in the Medicare value-based purchasing program.
Hypothesis testing
A statistical method that allows an analyst to measure the strength of evidence from the
data to reject or not reject a research hypothesis.
Inferential statistics
The branch of statistics dealing with conclusions, generalizations, predictions, and
estimations based on data from samples.
