Webinar on Data Presentation

Do you ever wonder when to use a line graph, bar chart, or pie chart? Or how your data might look different depending on which kind of tool you use? Then you might be interested in data presentation, the process of deciding which tool to use and what elements to employ.

We are delighted to share the webinar below, hosted by Tierney Steelberg, with you. She’ll lead you through the kinds of questions you can ask yourself so you and your students can make charts, graphs, and tables that communicate more clearly and completely.

Enjoy!

Data of the Day: Pie Slices!

Often, when students make pie charts, they end up with several very narrow slices. One thing we can encourage our students to do is think about what happens to their readers’ comprehension when the slices get so narrow that they’re almost impossible see.

Here’s a rule of thumb to consider:

Image that reads, "Rule of Thumb: Too many categories on a pie chart can actually reduce comprehension."

Data of the Day: the power of small multiples (NYTimes)

Small multiples is a data visualization term referring to placing several small graphics (either all charts, all graphs, all maps, etc.), where the scale (axes, etc.) are the same but the data is different. Here’s a great example from the New York Times.
The presence of small multiples means we can track drought patterns over decades within a very small space, as shown in the clip below.
This can be a great accompaniment to a high school study of the Dust Bowl, for example.
