Data Types
What is data that is organized into clearly defined fields, often in rows and columns?
What is Structured Data?
What is the measurement of the accuracy, completeness, consistency, and reliability of data?
What is Data Quality?
What is the process of discovering patterns, correlations, and trends in large datasets using statistical and computational techniques?
What is Data Mining?
What is the statistical relationship between two variables, indicating how one variable may change as the other does, without implying a cause?
What is Correlation?
What is the process of using technology to analyze data and provide actionable insights to help businesses make informed decisions?
What is Business Intelligence? What are Business Analytics?
What is data that does not follow a predefined model or organizational framework, such as emails, images, or videos?
What is unstructured data?
What is a large storage repository that holds vast amounts of raw, unstructured, and structured data in its native format?
What is a Data Lake?
What is the type of analytics that focuses on summarizing historical data to identify trends and patterns?
What is Descriptive Analytics?
What is the relationship where one variable directly affects or determines the outcome of another variable?
What is Causation?
What is a step-by-step procedure or set of rules designed to solve a problem or perform a computation?
What is an Algorithm?
What is a massive volume of data that is too large or complex to be processed using traditional methods?
What is Big Data?
What is the maintenance of data accuracy and consistency throughout its life cycle?
What is Data Integrity?
What is the type of analytics that suggests actions or decisions by evaluating various outcomes and determining the best course of action?
What is Prescriptive Analytics?
What are data points that are significantly different from other observations in a dataset and may indicate variability, errors, or novel insights?
What are Outliers?
What is the graphical representation of data, making it easier to understand trends, patterns, and outliers through charts, graphs, and maps?
What is Data Visualization?
What is data that can be measured and expressed numerically, often used in statistical analysis?
What is Quantitative Data?
What is the sequence of stages through which data progresses, from its initial generation and capture to its eventual archival or deletion?
What is the Data Life Cycle?
What is a computational model inspired by the human brain, consisting of layers of interconnected nodes (neurons), used in machine learning to recognize patterns and make decisions?
What is a Neural Net?
What is the statistical method used to model the relationship between a dependent variable and one or more independent variables, often for predicting outcomes?
What is Regression?
What is a set of rules and protocols that allow different software applications to communicate with each other, often used to access data or functionality?
What are APIs (Application Programming Interfaces)?
What is data that describes characteristics, qualities, or categories, and is often collected through observations or interviews?
What is Qualitative Data?
What is a repository used for reporting and data analysis, centralizing large volumes of data from different sources to support analytics?
What is a Data Warehouse?
What is the initial phase of analyzing data sets to summarize their main characteristics, often using visual methods, without making any assumptions?
What is Exploratory Data Analysis (EDA)? What is Data Discovery?
What is the process of making inferences or testing assumptions about a population parameter, based on sample data, using statistical methods?
What is Hypothesis Testing?
What is the standard language used to manage and manipulate databases, enabling users to query, update, and retrieve data?
What is SQL (structured query language)?
