Key Terms to Review (19)
Big data: Big data refers to the vast volume of structured and unstructured data generated every second, which is too complex and large for traditional data-processing software to handle. This term highlights the importance of collecting, storing, and analyzing these massive datasets to uncover insights and trends that can drive decision-making, particularly in fields like journalism. As technology advances, journalists increasingly rely on big data to tell stories, enhance reporting accuracy, and engage audiences with compelling narratives that are backed by quantitative evidence.
Correlation vs causation: Correlation refers to a statistical relationship between two variables, indicating that they change together, while causation implies that one variable directly influences or causes a change in another. Understanding the difference is crucial in data journalism because misinterpreting correlation as causation can lead to misleading conclusions and flawed reporting. Clear examples and careful analysis are essential to accurately convey the relationships between data points.
Dashboards: Dashboards are visual displays of data that provide a quick and easy way to monitor and analyze key metrics and performance indicators. They aggregate complex data sets into intuitive visuals, making it simpler for journalists and analysts to convey information clearly and effectively. This tool is particularly valuable in data journalism as it enhances storytelling by presenting data in a way that is accessible and engaging for the audience.
Data cleaning: Data cleaning is the process of correcting or removing inaccurate, incomplete, or irrelevant data from a dataset to improve its quality and ensure reliable analysis. This practice is essential in data journalism and data analysis, as it directly impacts the accuracy of insights derived from data. By refining datasets, journalists can effectively communicate stories and support their findings with trustworthy evidence.
Data journalism: Data journalism is the practice of using data as a primary source for news stories, focusing on the collection, analysis, and visualization of information to provide deeper insights and uncover patterns.
