Alignment of this item to academic standards is based on recommendations from content creators, resource curators, and visitors to this website. *It is the responsibility of each educator* to verify that the materials are appropriate for your content area, aligned to current academic standards, and will be beneficial to your specific students.

Essential and guiding questions:

- How did your results for the trials (your experimental values) compare to the expected value? Why do you think these differences occur between an experimental value and the expected value?
- Say you have a sample that contains only marked or only unmarked beans. How would that affect the inference you make about the population the sample was taken from?
- Explain the method(s) you used to fill in rows 7—10 on the Activity Sheet.
