Young analysts use real (provided) data from a class's test scores to practice using statistical tools. Not only do learners calculate measures of center and spread (including mean, median, deviation, and IQ range), but also use this information to draw conclusions about the underlying population. Histograms of data are also developed, making this a comprehensive worksheet for applying those abstract statistical concepts learned in class!

Instructional Ideas
- Activity could be extended so that students use the steps to test their own data
- Could be combined with computer class and lab time to learn spreadsheet software for data analysis and histogram creation
- Analysis could be used as the data for a statistical reports writing activity
Classroom Considerations
- Assumes students are already capable of performing data analysis since no method instruction is provided
- Not enough room on the worksheet to show work
Pros
- Real-life data for analysis
- Synthesis questions require more thought than straight computation questions
Cons
- Using two different teaching methods as a basis for analysis might undermine teaching efforts in future lessons
- Some equations didn't convert to pdf properly and resulted in some odd spacing / random floating fraction bar in the teacher key, specifically in the population mean calculation
- Analysis directions might lead to some confusion between correlation and causation
