Data Visualization Toolkit: Data Tables Data Considerations

Data Tables icon

A visual display can be helpful for generally comparing magnitudes or looking at trends, but sometimes providing specific data points is necessary. Data tables are useful for presenting data where specific data points, not just summary statistics or general takeaways, are important to the audience. Tables are also a good way to present both qualitative and quantitative data together.

Data Tables Data Considerations

Consider the degree of detail your audience needs for effective data-based decision-making. If trends or a comparison of general magnitudes is sufficient, consider summarizing them in a chart. However, if detailed data points are needed or your audience is there to help you better analyze the data, a data table is the better choice. When presenting data points, there is no rule of thumb as to how many digits to include. However, consider rounding the numbers as much as you can without losing their meaning or what differentiates them.

If you have a large amount of data to summarize in a data table, consider using an interactive data table (see screenshot in Figure 4) that allows the user to filter by the date or category of interest. Access the interactive data table to use filter.
