Active engagement enables direct learning (+-) Ambivalent One or more sentences p. 8 «When exposed to novel graphics, readers have to make an effort of understanding. Having made the effort, they have an emotional commitment to the graphic (nobody wants to admit they wasted their time). Whether they have actually learned anything useful is difficult to tell and would make for an interesting research study.» Streeb, Dirk: Feb. 27, 2018
Symbols carry „cultural“ meaning (+) Positive One or more sentences p. 8 «In addition, with familiar structures, visual conventions carry some of the work of exposition. Consider, for example, the use of the horizontal axis for a predictor variable and the vertical axis for the outcome» Streeb, Dirk: Feb. 27, 2018
Visualizations aid in communication / presentation (+) Positive One or more sentences p. 3 «An important part of statistical practice is graphical communication of data and models» Streeb, Dirk: Feb. 27, 2018
Visualizations are aesthetic (+) Positive One or more paragraphs p. 3 «We worry that designers of nonstatistical data graphics are not so focused on conveying information and that the very beauty of many professionally produced images may, paradoxically, stand in the way of better understanding of data in many situations.» Streeb, Dirk: Feb. 27, 2018
Visualizations are augmented with knowledge (+) Positive One or more sentences p. 8 «If they have a lot of background knowledge, they will view the graphic differently than if they rely only on the graphic and its surrounding text.» Streeb, Dirk: Feb. 27, 2018
Visualizations are combined with language (+) Positive One or more sentences p. 7 «To put it another way, a picture may be worth a thousand words, but a picture plus 1000 words is more valuable than two pictures or 2000 words.» Streeb, Dirk: Feb. 27, 2018
Visualizations are compact (+) Positive One or more sentences p. 7 «The picture tells the story as well as, and in less space than, the equivalent thousand words.» Streeb, Dirk: Feb. 27, 2018
Visualizations are discrete (+) Positive One or more sentences p. 22 «To use a literary analogy, statisticians tend to prefer Orwell’s (1946) dictum that “good prose is like a window pane,”» Streeb, Dirk: Feb. 27, 2018
Visualizations are easy to memorize (+) Positive One or more paragraphs p. 9 «We would probably remember a young man in green and white striped jeans better than one in a smart business suit. Does this mean we should dress exotically, if we want to be noticed? It obviously depends on what we want to be noticed for. The same goes for visualizations and we should think of graphics as being part of a whole, not viewing them in isolation.» Streeb, Dirk: Feb. 27, 2018
Visualizations do not require knowledge about rules of construction (?) Questioned One or more sentences p. 10 «The how-did-they-do-it and how-does-it-work aspects of Wordle overwhelm the data it was intended to display.» Streeb, Dirk: Feb. 27, 2018
Visualizations enable expertise building / implicit learning (*) Mentioned without valuation One or more sentences p. 8 «You need experience with a graphic form to use it well.» Streeb, Dirk: Feb. 27, 2018
Visualizations enable flexible usage (+) Positive Less than a sentence p. 4 «Exploratory graphics are all about speed and flexibility and alternative views.» Streeb, Dirk: Feb. 27, 2018
Visualizations leave room for human judgement (+) Positive Less than a sentence p. 4 «…graphics should enable readers to make up their own minds on any conclusions drawn…» Streeb, Dirk: Feb. 27, 2018
Visualizations make information understandable (+) Positive One or more sentences p. 7 «Displaying information from the dataset in a readily understandable way.» Streeb, Dirk: Feb. 27, 2018
Visualizations provide context (+) Positive Less than a sentence p. 4 «…provide more contextual information…» Streeb, Dirk: Feb. 27, 2018
Visualizations reduce effort (+) Positive Less than a sentence p. 4 «Exploratory graphics are all about speed…» Streeb, Dirk: Feb. 27, 2018
Visualizations relate model and data directly (+) Positive One or more sentences p. 11 «…the most effective data graphs can often be viewed as implicit or explicit comparisons to models (Gelman2004), and, conversely, when graphing models, we prefer to display data alongside to give a sense of model fit.» Streeb, Dirk: Feb. 27, 2018
Visualizations re-represent structures (+) Positive Less than a sentence p. 4 «Exploratory graphics are all about speed and flexibility and alternative views.» Streeb, Dirk: Feb. 27, 2018
Visualizations reveal false assumptions (+) Positive One or more sentences p. 7 «Giving an overview—a qualitative sense of what is in a dataset, checking assumptions, confirming known results, and looking for distinct patterns.» Streeb, Dirk: Feb. 27, 2018
Visualizations show additional relationships (+) Positive Less than a sentence p. 4 «Providing the right comparisons is important, numbers on their own make little sense…» Streeb, Dirk: Feb. 27, 2018
Visualizations show visual patterns (+) Positive One or more sentences p. 7 «Giving an overview—a qualitative sense of what is in a dataset, checking assumptions, confirming known results, and looking for distinct patterns.» Streeb, Dirk: Feb. 27, 2018

(Visualizations make information understandable <-needs to be traded off against-> Visualizations are aesthetic) (*) Mentinoed Basically all of the publication p. 9 «Some people deliberately choose to present fancy graphics that look pretty but are not interpretable. In other words they use graphics to hide information while appearing to do the opposite.» Streeb, Dirk: Feb. 27, 2018
(Visualizations make information understandable <-needs to be traded off against-> Visualizations are compact) (*) Mentinoed One or more sentences p. 7 «Information density is great, but only if this information can be visually extracted from the graph!» Streeb, Dirk: Feb. 27, 2018
