The following example illustrates the complete statistical problem-solving process at the level expected of a middle-school teacher.

1. Formulate Questions
Statistical investigations undertaken in elementary school are typically based on questions posed by the teacher that can be addressed using data collected within the classroom. In middle school, the focus expands beyond the classroom, and students begin to formulate their own questions. Because many investigations will be motivated by students’ interests, middle-school teachers must be skilled at constructing and refining statistical questions that can be addressed with data.
2. Collect Data
3. Analyze Data
4. Interpret Results
