Project Rubric

Opening

Project Rubric

Work with a partner and review the project rubric.

  • Take two minutes to study the rubric on your own.
  • Then have one partner (without looking at the rubric) take one minute to describe the rubric as completely as possible to the other partner (who can see it). This partner should listen carefully to the description.
  • Briefly look at the rubric again together. The partner who was previously the listener should now take 30 seconds to add to the description—without repeating any of it.

Math Mission

Opening

Organize and analyze your project data in order to answer your statistical question.

Organize and Analyze Project Data

Work Time

Organize and Analyze Project Data

Organize and analyze the data you collected for your project. Consider these questions:

  • What measures can you calculate to help you draw conclusions and to provide support for your conclusions? Examples: mean, median, mode, range, outliers, lower and upper extremes, lower and upper quartiles
  • What graph(s) will best represent your data? Examples: line plot, box plot, histogram, or more than one graph

Hint:

Keep the rubric in mind as you work on your project.

Prepare a Presentation

Work Time

Prepare a Presentation

Work on preparing your project presentation.

  • Make sure your completed project presentation includes the following:
    • Your data set
    • At least one graph and an explanation of why the type of graph you used best represents your data
    • Measure of center and/or spread
    • A summary of what the graph and measures tell you about your data
    • Your conclusion about what is typical for your set of data

Challenge Problem

  • Suppose you had collected twice as much data. Do you think having twice the amount of data would change your conclusion, or reinforce it?
  • Which of your measures would change? How would your graph(s) change?

Make Connections

Performance Task

Ways of Thinking: Make Connections

Look at the rubric again.

  • Notice the blank column with the heading Specific to This Project. Is there anything that you think should be added to this column?
  • Next look at the blank row at the bottom of the rubric. Is there any aspect of the statistics project that you think should be added here?
  • Take a few minutes to discuss these questions with your partner. Write down any ideas you have.
  • Be prepared to discuss your ideas as a class. As you propose an idea, make sure to say why you think it is important. After all ideas are discussed, the class will decide as a group whether to adopt any of the suggestions.

Measures of Center and Spread

Formative Assessment

Measures of Center and Spread

Complete this Self Check by yourself.

This box plot shows a summary of a data set of 10 measurements, each measured to the nearest inch.

  • Create a possible data set so that the mean of the data set is 15 inches.
  • Show your work and explain how you created the data set.
