Depicting Data (adapted in part from Mandeville) Graphical displays help make sense of raw data. Can be an aid in analysis Should enhance overall communication Involves choices about what/how to display What do you want to say? Are you trying to inform? Persuade? Who do you want to say it to? Does data help to tell the story?
Depicting Data Should tell a story (i.e. trends over time, patterns) Relate back to the whole Offers possibility of projections and comparisons
Common Types of Visuals Graphs/histograms Bar charts Pie charts Line charts http://www.statcan.ca/english/edu/power/ch9/piecharts/pie.htm Pictures/Concept maps Data mapping Tables
Improving Communication Double-check data Keep the message simple Visuals should be able to speak for themselves if done well Be sure sequence is logical Remember- different displays can impact message
Choosing Displays If data is mostly qualitative/textual tables are often preferable Quantitative data can often be best displayed in histograms and graphs In particular, quantitative data with 5 or more data points are usually best displayed in graphs
