Data Handling: How are data communicated in Real World?

Statistical representations are widely used to 'simplify' or 'summarise' data when presented along with reports.

An example is the a recent report on the "Alarming rise in losses on consumer prepayments" (Straits Times, 1 August 2017). Look at the bar chart presented. Did you notice how huge amounts is presented on the vertical axis?

In these two weeks (3 to 12 August), you shall look out for examples of charts used in reports any of the following and share with the class how charts are used in our daily life.

It would be even better if you could spot charts do not present the data appropriately or are misleading; and tell us why it's not appropriate or misleading.
Any duplicated charts, regards who posted it first will not be counted in group points.

How points are awarded:
  • Chart: Appropriate OR Misleading [1 pt]; 
  • Description of what chart attempts to communicate [1 pt];
  • If it is a misleading chart - elaborate why it is misleading [1 pt]
  • Acknowledge source (URL of source) [1 pt]
