SMART analytics principle
A goal-setting technique that stands for specific, measurable, attainable, relevant, and timely.
Primary data
Data collected for a specific purpose.
Secondary data
Data that relies on existing data collected for another purpose.
Structured data
Data organized in rows and columns, easily searchable and analyzable.
Unstructured data
Data without a predefined structure that does not fit well into a table format.
Discrete data
Data measured in whole numbers.
Continuous data
Data that includes values with decimals.
Categorical data
Data that represents a group of categories.
Binary categorical data
Categorical data having only two values, like yes or no.
Nominal categorical data
Data with characteristics that have no meaningful order.
Ordinal categorical data
Data with characteristics that hold a meaningful order, but uneven intervals between values.
Independent variable
The predictor or feature variable in an analysis.
Dependent variable
The variable being predicted in an analysis.
Predictive analytics
Analytics used to build models based on past data to explain future outcomes.
Prescriptive analytics
Analytics that identifies the best optimal course of action based on data.
Cognitive analytics
Advanced analytics capabilities that draw conclusions from data without being explicitly programmed.
Characteristics of Big Data
Volume, variety, veracity, velocity, and value.
Foreign key
A column or set of columns in a table that refers to the primary key in another table.
Relational data access
Accessed using structured querying language (SQL).
Aggregation (data transformation)
The process of summing data according to the unit of analysis desired.
Normalization (data transformation)
Scaling a variable by subtracting it from the mean and dividing by the standard deviation.
Dummy coding
Creating a dichotomous value from a categorical value.
Machine learning
The development of algorithms that allow computers to learn from experience.
Deep learning
Using algorithms to build neural networks for classification or prediction.
Natural language processing (NLP)
AI branch to identify patterns from human language.
Computer vision
A machine’s ability to extract meaning from images.
Exploratory data analysis
Summarizing main characteristics within data to explore trends.

Confidence (association metrics)
Measures the conditional probability of a consequent given the antecedent.
Lift
Evaluates the strength of an association between items.
Text analysis steps
Text acquisition, preprocessing, exploration, and modeling.
Node (social networks)
An entity like a person or product in a network.
Edge (social networks)
Links and relationships between nodes.
Degree centrality
Centrality measured by the number of edges connected to a node.
Betweenness centrality
Measures how often a node is on the shortest path between nodes.
Closeness centrality
Measures the proximity of a node to all others in the network.
Eigenvector centrality
Measures the linkage of a node to other well-connected nodes.
Sessions (web analytics)
Total visits to a website.
Conversion rate
Percentage of sessions resulting in goal completion.
Bounce rate
Percentage of users who leave after viewing only one page.
A/B testing
Method to test the effectiveness of various versions of web ads.
