Instructional Ideas
- Use statistics software to calculate several sample groups of varying sizes to show that the larger the sample size, the smaller the sample variability
- Lead a discussion about the balance of getting a large enough sample size and keeping the sample size manageable
Classroom Considerations
- Individuals must be able to build and read a dot plot
Pros
- Provides an axis to sketch dot plots
- Includes an exit ticket to assess understanding of the major concepts
Cons
- None
