You're struggling to make sense of a complex dataset. How can data visualization help you think critically? (2024)

Before you dive into a complex dataset, you need to have a clear purpose and a set of questions that guide your exploration. Data visualization can help you generate and refine your questions by showing you the overall structure, distribution, and relationships of the data. For example, you can use a histogram to see how the data is spread across different ranges, a scatter plot to see how two variables are correlated, or a map to see how the data varies by location. These visualizations can help you identify gaps, outliers, or anomalies that spark your curiosity and lead to more specific questions.

Once you have your questions, you need to find and evaluate the evidence that supports or refutes them. Data visualization can help you analyze the evidence by making it easier to filter, sort, and compare the data. For example, you can use a bar chart to compare the frequency or magnitude of different categories, a line chart to show the change over time of a variable, or a pie chart to show the proportion of a whole. These visualizations can help you see the differences, similarities, and trends that reveal the strength or weakness of the evidence.

After you have analyzed the evidence, you need to draw logical and valid conclusions that answer your questions. Data visualization can help you draw conclusions by making it easier to synthesize, interpret, and test the data. For example, you can use a dashboard to combine multiple visualizations that show different aspects of the data, a heatmap to show the intensity or density of the data, or a tree map to show the hierarchy or breakdown of the data. These visualizations can help you see the big picture, the details, and the connections that inform your conclusions.

Finally, you need to communicate your conclusions to others in a clear and convincing way. Data visualization can help you communicate your results by making it easier to present, explain, and persuade with the data. For example, you can use a story to guide your audience through a sequence of visualizations that illustrate your findings, a chart to highlight the key points or comparisons that support your arguments, or an interactive visualization to engage your audience and invite them to explore the data themselves. These visualizations can help you convey your message, your evidence, and your implications with the data.
