Teach: Average

Average

In this lesson, you will learn about the especially important concept of “average” in using data. Rather than simply memorizing words, you will aim to explain the mechanisms and reasons in your own words.

Key Point
When the total is divided by the number of items, the result is the average, which is one item’s share when everything is made equal in size.
Important Points
  • Check the reasons, not only the conclusion
  • Distinguish similar terms and exceptions
  • Try to see whether the same way of thinking can be used with other examples

Practice

  1. Explain the key point in two sentences.
  2. Give one common misconception and explain what is different about it.
  3. Check it by applying it to a familiar or specific example.
