In this lesson, you will learn about "descriptive statistics," one of the most important topics in data science. Rather than memorizing words alone, aim to explain the mechanisms and reasons in your own words.
Key Point
Looking at measures of central tendency together with variation makes it possible to distinguish distributions that have the same center but differ in other ways.

Important Point
- Check the reasons, not just the conclusion
- Distinguish similar terms and exceptions
- Try applying the same way of thinking to other examples
Practice
- Explain the key point in two sentences.
- Give one common misconception and explain how it differs.
- Check it by applying it to a familiar or concrete example.
