Agenda

Exploratory vs. Explanatory Analyses

  • What is the difference between exploratory and explanatory analyses?

Exploratory vs. Explanatory Analyses

  • Exploratory:
    • use of descriptive statistics
    • usually a larger number of data points
    • multiple views and interaction can help here
  • Explanatory:
    • use of inferential statistics
    • causation might be established

Remember: correlation does not mean causation

So what?

  • 3-minute story: if you had only three minutes to tell your audience what they need to know, what would you say?

  • Big Idea: The Big Idea boils the so-what down even further: to a single sentence.

3-minute story – Example

A group of us in the science department were brainstorming about how to resolve an ongoing issue we have with incoming fourth-graders. It seems that when kids get to their first science class, they come in with this attitude that it’s going to be difficult and they aren’t going to like it. It takes a good amount of time at the beginning of the school year to get beyond that. So we thought, what if we try to give kids exposure to science sooner? Can we influence their perception? We piloted a learning program last summer aimed at doing just that. We invited elementary school students and ended up with a large group of second and third-graders. Our goal was to give them earlier exposure to science in hopes of forming positive perception. To test whether we were successful, we surveyed the students before and after the program. We found that, going into the program, the biggest segment of students, 40%, felt just “OK” about science, whereas after the program, most of these shifted into positive perceptions, with nearly 70% of total students expressing some level of interest toward science. We feel that this demonstrates the success of the program and that we should not only continue to offer it, but also to expand our reach with it going forward.

Big Idea

The pilot summer learning program was successful at improving students’ perceptions of science and, because of this success, we recommend continuing to offer it going forward; please approve our budget for this program.

Exercise – select a story to tell

What problems are you interested in solving?

What would your 3-minute story? And our Big Idea?

Storyboarding

  • Visual outline

“It can be subject to change as you work through the details, but establishing a structure early on will set you up for success. When you can (and as makes sense), get acceptance from your client or stakeholder at this step. It will help ensure that what you’re planning is in line with the need.”
