Predictive analysis uses statistical approach to analyze large volumes of data.TruePredictive analysis is developed from the fields of statistics, computer science and computer engineering.TrueOutput variable is the primary factor that is evaluated for a predictive test.TrueDependent variable is the input to the formula in any statistical method.FalseTechnical is the most important of the three layers of excellence of an analytical HCO.FalseTechnical infrastructure must be robust.TrueStrategic activities help building a sustainable analytics infrastructure.TrueHCOs must pursue execution excellence.TrueAnalytics teams must be agile.TrueAccuracy is one of the data quality dimensions.TrueFinding new relations between the process and outcomes is only possible when the data is integrated across the organization.TrueA list of activities associated with maintaining a healthcare data system that supports the needs of an HCO includes data storage and data usage.FalseA list of activities associated with maintaining a healthcare data system that supports the needs of an HCO includes data modeling, data creating, data storage and data usage.True"Multiple data sources" is one of the major causes of data quality problems.TrueGrades (A,B,C,D,F) are the examples of Ordinal data.TrueThe standard deviation, the mean, and the median are the three most common measures of central tendency.FalseThe mean is the ariphmetic average of a data set.TrueMedian is susceptible to outliers.FalseThe mean and median can never be equal.FalseKey Performance Indicators (KPIs) do not need to be reported frequently.FalseKey Performance Indicators (KPIs) focus on the aspects that are most critical for the success of the organization.TrueSMART: Specific, Metric, Actionable, Relevant, Time-boundFalseKey Performance Indicators and their associated targets should be time-bound.TrueKey Performance Indicators (KPIs) are expressed in non-financial measures.TrueBaseline data are based on the indicators developed for the QI project.TrueBaseline performance data is a quantitative description of some aspect of an organization's performance measured prior to undertaking an improvement initiative.TrueIdentifying possible counter measures to address root causes" is one of the steps in identifying and selecting improvement opportunities.TrueIs the following order of five QI phases correct: Define the problem => Identify opportunities => Execute improvement activities => Evaluate outcomes => Sustain changesTrueVolume of data does not cause data quality problems.FALSEData Stewardship is the ultimate authority on how data is managed throughout the enterprise.FALSEData is a static asset within a healthcare organization.FALSEThe mode is the most commonly occurring value in a data set.TRUEThe mean, the median and the mode are the three most common measures of central tendency.TRUEValues which are mutually exclusive and follow a specific order are called categorical data.FALSEOne-sample t-test is used to compare the performance of two groups.FALSEHypothesis testing is the use of statistics to determine the probability that a given hypothesis is true.TRUEStatistical tests do not utilize aggregated data.FALSEInferential statistics are used to draw conclusions about a population using a sample and often include such methods as hypothesis testing.TRUEDescriptive statistics are used to describe the basic features of the data in a study and often include such measure as the mean, median, standard deviation, etc.TRUEStatistical control charts (SPC) can highlight the changes in the process performance.TRUEThe starting point of all data visualizations is to select an appropriate visualization approach.FALSEAutomation enhances the usability of analytics.TRUEPoorly designed portal is the main barrier to "self-serve".TRUEEnd users must be involved in the design of dashboards.TRUEInconsistency is one of the data quality dimensions.FALSEHCOs require strong and effective data governance strategies and structures. As data owners, HCOs have a responsibility for: Data quality, Privacy and security, Business rules, Availability, Periodicity, and Performance.TRUEIs the information value chain presented below in the correct order? Information --> Analysis--> Data --> Action --> OutcomesFALSEData type defines what operations can be performed on data stored in a database.TRUERelevant and actionable are the two most important qualities of indicators.TRUEKPI stands for Key Performance Image.FALSEData quality might not be an issue if baseline data are collected manually.FALSEBaseline data do not have to be based on and measured in the exact same way as the indicators developed for the QI project.FALSEStatistical methods are used to identify unusual variations in the performance.TRUEHypothesis testing involves a test of statistical significance.TRUEStatistics provides methods to analyze quality and performance of data.TRUEStatistical procedures can be divided into two major categories: descriptive statistics and inferential statistics.FALSECauses of poor chart usability include explanation, discrimination, and construction.TRUEEMR stands for Electronic Medical RecordsTRUEPatient is the person who supports and provides financial resources for the development and implementation of the analytics infrastructureFalseCustomer/user is a person within the HCO who accesses analytical tools, or uses the output of analytical tools, to support decision making and to drive actionsFalseAs a general rule of thumb, somewhat between 5 percent and 20 percent of activity in healthcare can be considered value-added, whereas the remainder is considered non-value-addedTrueDMAIC stands for Detect-Measure-Act-Improve-ControlFalseDMAIC stands for Define-Measure-Analyze-Improve-ControlTrueVSM stands for Value Stream MapTruePDSA stands for Plan-Do-Study-ActTrueHIT stands for Health Informatics TechnologyFalseInfluencer is a person who may not be directly involved in the development or use of analytics within the HCO, but who holds considerable influence (positive or negative) over the support of analytics initiativesTrueAnalytics consists of the tools and techniques to explore, analyze, and extract value and insight from healthcare dataTrueBI stands for Big IntelligenceTrueSkill sets useful for Healthcare Analytics Professionals: Communications Technical Clinical Quality improvement AnalyticalTRUEQuality is the degree to which health services for individuals and populations increase the likelihood of desired health outcomes and are consistent with current professional knowledgeTrueThere is one QI methodology used in healthcare today - Six SigmaTrueThere are three components of Healthcare Quality Measurement: Structure, Process, and OutcomesTrueAs a general rule of thumb, somewhat between 5 percent and 20 percent of activity in healthcare can be considered non-value-added, whereas the remainder is considered value-addedFalseAccuracy is one of the data quality dimensions.True"Identifying possible counter measures to address root causes" is one of the steps in identifying and selecting improvement opportunities.TrueIs the following order of five QI phases correct:
