Key Terms to Review (18)
Ben Welsh: Ben Welsh is a prominent figure in the field of data journalism and open data advocacy, known for his work in enhancing transparency and accountability through the analysis of government and institutional databases. He has played a significant role in promoting data-driven storytelling, encouraging journalists to leverage data to uncover important stories and engage the public.
Census data: Census data refers to the comprehensive collection of demographic, social, economic, and housing information obtained from a population at regular intervals, typically conducted every ten years. This data is crucial for understanding population characteristics, informing policy decisions, and allocating resources in various sectors, including government, healthcare, and education.
Criminal justice databases: Criminal justice databases are organized collections of data that store and manage information related to criminal justice, including criminal records, arrest data, court cases, and law enforcement activities. These databases facilitate the efficient retrieval of critical information for law enforcement agencies, legal professionals, and researchers, playing a vital role in crime analysis and prevention.
Data accessibility: Data accessibility refers to the ease with which users can obtain and utilize data from various sources, ensuring that information is available to those who need it for analysis and decision-making. This concept is crucial in promoting transparency and accountability, especially when dealing with government and institutional databases that contain important public information.
Data bias: Data bias refers to systematic errors in data collection, analysis, interpretation, or presentation that lead to inaccurate conclusions or representations. It can stem from various factors, including how data is gathered, who is included in the dataset, and the methods used for analysis, ultimately skewing the results and influencing decisions based on flawed information.
Data lag: Data lag refers to the delay between the time data is collected and when it becomes available for analysis or use. This delay can impact decision-making, especially in rapidly changing environments where timely information is crucial for understanding trends and making informed choices.
Data mining: Data mining is the process of discovering patterns and extracting valuable information from large sets of data using various analytical techniques. It plays a crucial role in journalism by helping researchers and journalists uncover trends, insights, and stories hidden within vast amounts of data, thus enhancing the overall quality of reporting and analysis.
Data privacy: Data privacy refers to the proper handling, processing, storage, and protection of personal information that individuals share online or in other contexts. It emphasizes the importance of safeguarding sensitive data against unauthorized access, breaches, and misuse, while ensuring compliance with legal regulations and respecting individual rights. This concept is crucial in understanding how government databases are managed, the ethics of data journalism practices, and the implications of big data on individuals' privacy rights.
Data visualization: Data visualization is the graphical representation of information and data, allowing complex data sets to be understood and communicated more easily.

Statistical significance: Statistical significance is a mathematical determination that indicates whether the observed results in a study are likely to be genuine or if they could have occurred by random chance. It is typically assessed using a p-value, which helps researchers understand if the findings from their data analysis are reliable enough to draw conclusions. Establishing statistical significance is crucial for validating claims based on research and understanding the real-world implications of data.
Triangulation: Triangulation is a method used in research to cross-verify information by using multiple sources or methods to ensure accuracy and credibility. This approach is crucial for enhancing the reliability of findings, as it allows researchers to compare different data points and perspectives, thereby painting a more comprehensive picture of the subject under investigation.
