Practice and reflection

Check the idea, then explain it.

Try these questions after the lessons. Responses remain in your browser and are not submitted. The questions are informal checks, not a graded or validated assessment.

1. In a light-versus-growth study, which variable is measured?
2. What is the mean of 2, 4, and 6?
3. Does “my design is best” count as evidence?

Transfer your understanding

For each question, explain why one alternative is incorrect. Then create your own example that illustrates the correct idea. Recognition is a starting point; explanation shows how the ideas connect.
