Lecture 25 & 26 Visualization and social media monetization

Key takeaway from the video, Hans Rosling shows the best stats you've ever seen

  • Observe data in different dimensions trend/moving pattern over time, record the moving paths to perceive past trend and predict future pattern (Use data to do projection based on the past pattern)
  • Visualize data based on reasonable measure, such as population
  • Show graphs by both Aggregate data and split data
    • Dangerous to only use average data (can't see the big picture), since the details can be much different from average. Also, average can be affected by outlier and misrepresent the truth. 
  • Clearly show over time and regional pattern
  • Link data with internet the draw the whole picture and tell story about the data
  • Explain the behavior of the data - not just how data is moving but why
  • Volume of data makes things different - "big data" to be representative
  • How to Access to data and Cleaning of data are important
  • Present data in a visually appealing way
  • Data is not always in/about a company, rather, data outside the company, such as industry trend, is also important to predict future.
