data journalism unit 13 study guides

Key Concepts and Principles

• Data journalism combines traditional journalism with data analysis to uncover insights and tell compelling stories
• Involves collecting, cleaning, analyzing, and visualizing data to support and enhance reporting
• Requires a combination of journalistic skills (research, interviewing, writing) and technical skills (data wrangling, statistical analysis, programming)
• Enables journalists to find patterns, trends, and outliers in large datasets that may not be apparent through traditional reporting methods
• Allows for data-driven decision making and evidence-based reporting
  • Provides a foundation for more objective and transparent journalism
  • Helps journalists avoid relying solely on anecdotal evidence or personal biases
• Facilitates the creation of interactive and engaging visualizations (charts, maps, infographics) to convey complex information in an accessible way
• Promotes transparency by allowing readers to explore the data behind the story and draw their own conclusions
• Encourages collaboration between journalists, data analysts, and designers to create impactful and informative stories

Data Collection Techniques

• Web scraping involves using automated scripts or tools to extract data from websites and online sources
  • Requires knowledge of HTML structure and programming languages (Python, R)
  • Useful for gathering data from multiple pages or sites efficiently
• Freedom of Information Act (FOIA) requests enable journalists to obtain government records and documents
  • May require persistence and follow-up to ensure timely and complete responses
• Surveys and polls can be conducted to gather original data on specific topics or issues
  • Requires careful design and sampling to ensure representativeness and minimize bias
• Interviews with experts, stakeholders, and affected individuals provide context and human perspectives to complement data findings
• Crowdsourcing involves soliciting data or information from a large group of people, often through online platforms or social media
• Public databases and datasets (Census Bureau, World Bank, United Nations) offer a wealth of information on various topics
• Partnerships with academic institutions, research organizations, or data providers can provide access to specialized datasets and expertise

Analysis Methods and Tools

• Descriptive statistics (mean, median, mode, standard deviation) summarize and describe key features of a dataset
• Inferential statistics (hypothesis testing, regression analysis) enable journalists to draw conclusions and make predictions based on data
• Data cleaning involves identifying and correcting errors, inconsistencies, and missing values in a dataset
  • Requires attention to detail and knowledge of data quality issues
  • Tools like OpenRefine and Trifacta can automate and streamline the cleaning process
• Exploratory data analysis (EDA) is the process of visualizing and summarizing data to identify patterns, trends, and relationships

  • Techniques include sentiment analysis, topic modeling, and named entity recognition
  • Tools like NLTK and spaCy provide natural language processing capabilities

Visualization Strategies

• Choosing the right chart type (bar chart, line chart, scatterplot) depends on the nature of the data and the story being told
  • Consider the variables being compared, the level of detail needed, and the intended message
• Interactive visualizations allow readers to explore the data and discover their own insights
  • Tools like D3.js and Plotly enable the creation of dynamic and interactive charts and graphs

  • Require careful design and layout to ensure clarity and visual appeal
  • Tools like Adobe Illustrator and Canva provide templates and design elements for creating infographics
• Data animations can show changes or trends over time in an engaging and dynamic way
  • Tools like GIF and After Effects enable the creation of data-driven animations
• Accessibility considerations ensure that visualizations can be understood by all readers, including those with visual impairments
  • Use of color, contrast, and alternative text descriptions are important for accessibility
  • Tools like ColorBrewer and Highcharts provide options for creating accessible visualizations

Ethical Considerations

• Accuracy and transparency are essential for maintaining credibility and trust with readers
  • Data sources and methods should be clearly documented and available for scrutiny
  • Limitations and uncertainties in the data should be acknowledged and explained
• Privacy and security concerns arise when working with sensitive or personal data
  • Proper anonymization and aggregation techniques should be used to protect individual identities
  • Secure storage and access protocols are necessary to prevent data breaches or misuse
• Bias and fairness issues can arise in the collection, analysis, and presentation of data
  • Journalists must be aware of their own biases and strive for objectivity and balance in their reporting
  • Underrepresented or marginalized groups should be included and given a voice in data-driven stories
• Informed consent is necessary when collecting data directly from individuals
  • Participants should be fully informed of the purpose, risks, and benefits of the data collection
  • Opt-in consent forms should be used to ensure voluntary participation
• Ethical guidelines and codes of conduct (Society of Professional Journalists, Online News Association) provide frameworks for responsible and ethical data journalism
• Collaboration with ethicists, legal experts, and community stakeholders can help navigate complex ethical issues and ensure responsible reporting

Storytelling with Data

• Finding the human angle in data-driven stories helps to make the numbers relatable and compelling
  • Profiles of individuals or communities affected by the data can provide a human face to the story
  • Anecdotes and quotes can be used to illustrate key points and bring the data to life
• Narrative structure is important for guiding readers through the data and highlighting key insights
  • The inverted pyramid structure (most important information first) is a common approach in journalism
  • Other structures (chronological, problem-solution, compare-contrast) can be used depending on the nature of the story
• Contextualizing the data with background information and expert analysis helps readers understand the significance and implications of the findings
  • Historical data and trends can provide context for current events or phenomena
  • Expert interviews can provide insight into the causes, consequences, and potential solutions related to the data
