In this lesson, you will learn about “samples and errors,” 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
Select a sample so that it represents the population without bias, and interpret the results together with the sample size and margin of error.

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
Practice
- Explain the key point in two sentences.
- Give one common misunderstanding and explain how it is different.
- Apply it to a familiar or specific example and check your understanding.
