Teach: Manipulating Impressions with Graphs

Manipulating Impressions with Graphs

In this lesson, you will learn about “manipulating impressions with graphs,” one of the most important topics in interpreting statistics. Rather than memorizing words alone, you will aim to explain the mechanisms and reasons in your own words.

Key Point
Changing the starting point of an axis, the scale intervals, the aspect ratio, or the period covered can change the impression of differences even when the data are the same.
Points to Remember
  • Check the reasons, not just the conclusion
  • Distinguish similar terms and exceptions
  • Try using the same way of thinking with other examples
