What am I talking about? 2011 Unit 2 study design, Area of Study 1 Defining “Data Visualisation” Study design requirements What do we mean by “big databases” How can we teach this to our kids? Possible Project ideas
“A better experience through good design” goincase.com
Purpose Comparing data ‘Where is the web traffic coming from?’ Australia or USA -> Pie Chart Distribution of data ‘When are people accessing the web site?’ Morning or night? -> Column Chart Relationships between two data sets ‘Hits on the blog vs. Sales on online store’ -> Scatter Chart Composition of data How does the data change over time?
The Whitburn Project 120 years of chart history in the US Spreadsheet of 37,000 songs and 112 columns of raw data Relationship between song duration and length of stay in chart http://waxy.org/2008/05/the_whitburn_project/

Suitability Choose appropriate data for visualisation Students access big databases, understand what the data is telling them and then choose what they need to use.
Sites you should visit Australian Bureau of statistics http://www.abs.gov.au/ OECD http://www.oecd.org/ Google Public Data http://www.google.com/publicdata/directory
Implementing the Outcome Problem to be solved Kids accessing authentic data from large data repositories Local vs. global problems Presenting key aspects of the data in a visual form back to the client/user Suitability of data chosen Suitability of Data visualisation chosen
Possible examples Students have to visualise data to aid in decision making Sponsorship of Child Which country is in need of your money? Where should the soccer world cup go? Which country would benefit economically by the decision?
Example from the book Your school has sponsored a child in Sudan needs to choose another sponsor child Produce a series of data visualisations that would assist them with their decision. Identify three potential sponsorship children Use big databases (http://data.worldbank.org/) to choose suitable information about Health and Education Perhaps compare with Australian data Present a compelling presentation
