  1. Interactive VisualiZationsof statistics in RIP By: Tim de Boer and Kim Verkooij

  2. Data VisualiZation • The set of techniques used to turn a set of data into visual insight. • It aims to give the data a meaningful representation by exploiting • the powerful discerning capabilities of the human eye* Our focus: Interactive visualizationsof numeric data (statistics) * Edinburgh Online Graphics Dictionary http://homepages.inf.ed.ac.uk/rbf/GRDICT/grdict.htm

  4. Problem statement • “Upcoming computing capabilities provide a new medium for the invention of graphical methods for data analysis”* • "Some display methods lead to efficient, accurate visual decoding of encoded • information, and others lead to inefficient, inaccurate decoding" ** • Research question • Which visualizations and interactions are applicable for the representation of (numeric) statistics in RIP’s? * Richard A. Becker, William S. Cleveland, and Allan R. Wilks, ‘‘Dynamic Graphics For Data Analysis,’’ Statistical Science, Vol 2, 1987, pp 355-395. ** William S. Cleveland. A model for studying display methods of statistical graphics,

  5. Current state of research • Scientific research on statistical visualizations • Not within the context of RIP • Mostly for geographical visualisations • Journals • Journal of Statistical Science • Journal of the American Statistical Association • Keywords: • Dynamic/interactive visualization/graphics • statistical/scientific visualization

  6. Interactive Examples • Pivot tables • Motion charts • http://code.google.com/intl/nl-NL/apis/visualization/documentation/gallery/motionchart.html • Slice/drill down tables • http://code.google.com/intl/nl-NL/apis/visualization/documentation/gallery/linechart.html • http://code.google.com/intl/nl-NL/apis/visualization/documentation/gallery/piechart.html • http://code.google.com/intl/nl-NL/apis/visualization/documentation/gallery/scatterchart.html • … Interaction

  7. hypothesis • The enhanced interactive visualizations preferred for the first generation RIP’s do not differ that much from the conventional 2D visualizations used in paper publications. • Adoption of RIP’s is a process (dr. R. van Horik) • People are familiar with conventional visualizations • More data will get available when using enhanced visualizations for RIP’s • More data can be visualized • Using visualization tools, sharing data becomes easier • Linking of data becomes easier (SURF)

  8. Research method • Literature study • About 20 papers • Online survey: RIP readers • Goal: 50 participants • Google forms or home brew survey "It is only through rigorous studies of visual decoding that informed judgments can be made about how to choose display methods“* * William S. Cleveland. A model for studying display methods of statistical graphics,
