Experimental design can be both incredibly intuitive and very high-concept when first introduced to learners. This video does a great job of discussing sampling methods and bias simply, without over-reducing the complexity. Multiple examples are presented of both correct and incorrect experiment designs with methods for identifying and correcting problems. A great introduction or refresher in the importance of random sampling and bias prevention for young statisticians.

Instructional Ideas
- Divide the class into small groups and have each create and perform a skit demonstrating bias and how to fix it
- Bring in newspapers for the class to look for reported statistical results and discuss potential sampling methods and bias
- Invite a local statistician or PhD into class to discuss experimental design in their research or field
Classroom Considerations
- Video viewing requires the Internet
- Providing a script of the video might assist learners who need more processing time for the concepts discussed
- Consider pausing the presentation at regular intervals to allow for class questions and discussion
Pros
