Study Notes

Learning Objectives

Understand data's role in business intelligence (BI) and analytics (BA).
Prepare real-world data for analytics use.
Explore statistical modeling and its significance to BA.
Differentiate between descriptive and inferential statistics.
Recognize business reporting and its evolution over time.
Appreciate data/information visualization's critical role.
Learn various visualization techniques.
Understand the benefits of visual analytics in business.
Know dashboard capabilities and inherent limitations.

Nature of Data

Data transforms into actionable information.
Key attributes for analytics-ready data include reliability, accuracy, accessibility, security, consistency, currency, granularity, validity, and relevancy.

Data Taxonomy

Categorical data categorizes variables into specific groups, such as age or education level.
Nominal data uses simple codes that carry no numeric value.
Sampling techniques include balancing and stratification.

Statistical Modeling

Statistics involve techniques to interpret and analyze data.
Descriptive statistics summarize data as it is.
Inferential statistics make predictions or inferences about larger populations using sample data.

Descriptive Statistics

Central tendency measures: Mean (average), median, and mode.
Dispersion measures include range, variance, standard deviation, and Mean Absolute Deviation (MAD).
Skewness and kurtosis evaluate data distribution shape.

Regression Modeling

Regression, a key component of inferential statistics, explores relationships between explanatory (input) and response (output) variables.
Used for hypothesis testing and predicting outcomes.
Differentiates between correlation and regression, with simple regression utilizing one input variable and multiple regression using more than one.

Time Series Forecasting

Focuses on time-varying behavior, such as moving averages and cyclical trends.

Business Reporting

A report communicates information for decision-making.
Reports can serve multiple functions: ensuring departmental functionality, providing insights, fostering analysis results, persuading action, and maintaining organizational knowledge.
Business reports improve managerial decision-making using data from internal and external sources, typically formatted with text, tables, and graphs.

Types of Business Reports

Metric Management Reports: Drive performance management using metrics like Service Level Agreements (SLAs) and Key Performance Indicators (KPIs).
Dashboard-Type Reports: Graphically present multiple performance indicators on one page with dials or gauges.
Balanced Scorecard Reports: Incorporate financial, customer, process, and learning indicators.

Data Visualization

Utilizes visual representations to explore, analyze, and communicate data.
Involves information aggregation, summarization, and contextualization, often through charts and graphs.

Emergence of Data Visualization

Increased emphasis from prominent companies, including Tableau, QlikView, and Microsoft.
Technologies integrate big data, in-memory processing, and analytics into visualization tools.

Performance Dashboards

Visual displays consolidate vital information for quick comprehension and exploration.
Effective dashboard design focuses on clarity, minimal distraction, and information assimilation.
Dashboards combine diverse data sources into unified views, enabling drill-down access and providing real-time updates.

Best Practices in Dashboard Design

Benchmark Key Performance Indicators (KPIs) against industry standards.
Embed contextual metadata with metrics.
Validate design with usability specialists.
Prioritize alerts and present information at three levels.
Utilize appropriate visual constructs and guided analytics.

Business Performance Management (BPM)

BPM operates in real-time to inform managers of opportunities and threats, facilitating proactive responses through collaboration and modeling.
Also referred to as Corporate Performance Management (CPM) or Enterprise Performance Management (EPM).
BPM encompasses methodologies, metrics, and technologies to measure and manage business performance.
