Understanding Data Analysis

WNCP:

 Outcome SP6.1: Extend understanding of data analysis to include: line graphs graphs of discrete data data collection through questionnaires, experiments, databases, and electronic media interpolation and extrapolation. Indicators: Construct a graph (line graph or a graph of discrete data points) to represent data given in a table for a particular situation

Lesson Preparation:

Equipment/materials:
• 4 Sticks of equal length and width. Two sticks have stripes on one side and the other two sticks have crosses on one side.

Game sticks can alternately be made with Popsicle sticks.

• Have sticks prepared for student’s usage.
• A copy of the activity sheet for each student.
• Have the scoring table displayed on an overhead so that all the students can see it.
• Have the example activity sheet displayed on an overhead so that all the students can see it.

Activity/Lesson Ideas:

The game called Chekutnak or Stick Dice is described in the games section of Aboriginal Perspectives. For this lesson we are going to modify the rules slightly.

The player drops or tosses the four sticks and points are awarded according to the table below.

Examples:

 A 3 point toss A 2 point toss

Arrange the students in pairs and give each pair a set of 4 sticks and two score sheets. Have each student put his or her name at the top of the score sheet. In each pair have the first student toss the sticks 10 times and have the second student record the score on each toss and the running total on the first student's score sheet. Have the students reverse roles so that the second student tosses the sticks and the first student records the score and running total on the second student's score sheet.

Have each student take his or her own scores sheet and construct a line graph of the score. In a different colour have each student costruct a line graph of the running total. An example is shown in the example score sheet.
