ND Curriculum Initiative

The North Dakota Curriculum Initiative (NDCI) is a long-term professional development program for North Dakota public and non-public school curriculum administrators and teachers.

Scatter Plots

For grade(s) 9-12.

SCATTER PLOTS
 
Tier 1:
Use the data below that shows the test scores and the number of absences related to the test score.
Test Score:     100     95     90    85     80     75     70     65     60     55     50
Absences:        0          2       3     3       5        7      8       9       11     12     15
     1.  Make a scatter plot of the data.
     2.  Make a conclusion about the data.
     3.  Predict the test score of the six absence.
Tier 2:
Use the ordered pairs that give the heights, in inches, and the weights, in pounds, of seven Appaloosa horses.
     (56.1, 1000), (59.3, 1075), (58.5, 1020), (59.8, 1080), (61.4, 1090), (57.2, 1015)
     and (62.1, 1100)
     1.  Make a scatter plot of the data.
     2.  Make a conclusion about the data.
     3.  Predict the weight of an Appaloosa horse that is 60 inches tall.
 
Tier 3:
Choose a topic of your choice.  Gather and record your own data.
Examples:  surf the net for the homes on the market.  The selling price related to the square footage.  The weight of males/females related to their height, ball bounce:  the time it takes the ball to hit the ground in relation to the height that it is dropped at.
    1.  Make a scatter plot of the data.
     2.  Make a conclusion about the data gathered.
     3.  Make a prediction.

Subject & Standards

Mathematics:

Needs Assessment/Rational

To be able to collect and read data to make a prediction.

Equipment/Materials Needed

Depending on the student choices:             
Computer access, balls, stop watch, scale, ruler.

Understandings & Goals

I want my students to be able to plot points in a coordinate plane by gathering their own information.  To be able to draw a scatter plot and make predictions about real-life situations.

Questions Answered

If your house went on the market, what would it sell for?
How much does a horse weigh that is the same height as you?
Objectives:
1.  to gather, organize and display the information using coordinate geometry
2.  to draw conclustions and make a prediction

Assessment

Students can make a best fit line and predict. 

Instructional Strategies

This project based learning is to get the students engaged in learning through their own experiences or hands on.
