Note: If you landed here by searching on “datasaurus” (± “dozen”) and have no idea what SenseMaker is, you can jump to the graphical results. In an earlier post in this series, Part III: Random Data, I showed an example of a SenseMaker triad, with data clustered near vertices, along edges, and in the center; […]

Continue Reading...If you had asked me a year ago to identify the primary unit of observation in a SenseMaker project, I would have said, without much hesitation, it’s the story, of course. When I started writing Part IV in this series on Confidence Regions, however, I had to revisit that question. I knew what was typically […]

It’s a 2012 guest piece in The Atlantic by UCLA sociology professor Gabriel Rossman, merging two 2010 posts from his blog, Code […]

The familiar answer is given by error bars or confidence intervals in x-y plots or bar charts, assuming an appropriate statistical model, for example […]

It’s also common to find “stringers” between the center and one or more of the other six loci (i.e., along the altitudes of the triangle); there are generally […]

The two are meant to be read sequentially, since the mathematical elements of the first are an important and inescapable prerequisite for the second. If you already have a working knowledge of the geometric mean, however, and how its use differs […]

Its three vertices usually denote potential attributes, among which respondents can choose in any proportions, to amplify or augment their responses or reactions to some prompt about which […]
No Comments. Continue Reading...In my last post, I gave you a couple of triads and dyads to play with. Part of how I analyze story data is to see if there are statistical differences based on how respondents answer multi-choice questions (e.g., How common is this story?) and demographics (e.g., Primary geographic region where you work). In the […]

Last year I put together a collector that focused on Employee Satisfaction. It was never released as a project but I had a number of people contribute experiences, both real and made-up. (No, the stories […]
