**Essential Questions**

**Essential Questions**

- How can data be displayed, interpreted, analyzed, and compared?
- What is a statistical question, and why is it important when collecting data?
- What is the relationship among distance, rate, and time?
- How can rates be compared when they do not involve the same units?

**Concepts**

**Concepts**

- Measures of central tendency, histograms, stem-and-leaf plots, and box plots will be used to represent and compare data.
- The shape and spread of data will be interpreted and compared through visual displays and calculations.
- Statistical questions will be used to anticipate variability in the answers.
- Distance, rate, and time share the relationship of d=rt.
- Unit conversions are important when comparing rates.

**Skills**

**Skills**

- Collect and display data through the use of measures of central tendency, histograms, stem-and-leaf plots, and box plots.
- Interpret and compare the shape and spread of data both through visual displays and calculations.
- Evaluate whether a question is a statistical question.
- Calculate problems involving distance, rate, and time.
- Apply unit conversions so that they are the same and then use them to compare rates.
