It's All Scattered!

Task 1: Data Collection

1. Select two variables that can be measured or counted that you think will be related. The variables may apply to people or things. One variable may be from the Data Collection Sheet but not both. At least one of the variables must be a new one, not on the class list.


2. Collect new data (don’t use old class data) for the two variables on at least 20 different sources (people, trials, etc.). Data collection points are awarded for students that collect more than 30 sets of data.


When you complete Task 1, see Mrs. Garcia for your points.


Task 2: Analyze Your Data

1. Show that you understand your variables by describing them clearly in words.

2. Make a scatter plot for the variables.

3. Comment on whether the two variables appear to be related. If so, tell why. If you think there isn’t a relationship, tell why not.

4. Show that you understand the relationship by describing it clearly in words. Does one variable cause the other? What can you predict about other people that you did not survey?


When you complete Task 2, see Mrs. Garcia for your points.


Task 3: Presenting your Data

Use the information below to make sure you follow all the steps to completing this project.

  • My scatter plot is neatly drawn with equal spaces representing equal quantities in each axis

  • The number of items or people I measured or surveyed is ______ (must be more than 20, preferably 30).

  • My t-table is attached to my graph

  • My data points are carefully plotted.

  • I completed a written discussion of whether the scatter plot shows a relationship.

  • I completed a written discussion describing my variables and explaining whether there is a relationship and if one variable causes the other (causation).



When you complete Task 3, see Mrs. Garcia for your points.
