Review Questions

• How does data analysis contribute to uncovering potential investigative stories?
  • Data analysis allows journalists to sift through large amounts of information to identify trends and anomalies that may indicate deeper issues. By applying statistical techniques and tools, they can reveal patterns that are not immediately visible. This process helps in generating leads for stories that could highlight social injustices or governmental malfeasance.
• Discuss the role of quantitative versus qualitative research methods in the context of data analysis for investigative journalism.
  • Quantitative research methods focus on numerical data and statistical analyses, which can provide strong evidence for claims in investigative journalism. In contrast, qualitative research gathers detailed insights from interviews and observations, adding depth to the numerical findings. Using both approaches together enhances the overall understanding of a story and enriches the narrative with both hard data and human experiences.
• Evaluate how statistical significance impacts the interpretation of findings during data analysis in journalistic investigations.
  • Statistical significance plays a crucial role in determining whether findings from data analysis can be deemed reliable or if they occurred by chance. Journalists must evaluate this significance to make informed decisions about which trends or patterns are worth investigating further. Understanding statistical significance also helps in presenting credible evidence in reports, ensuring that the stories they tell are backed by solid, verifiable data.
