Exercises: Reading and Building Scatter Plots

Work through each section in order. When you read a scatter plot, look at the whole cloud of points, not one point at a time. Use the words positive, negative, linear, nonlinear, cluster, and outlier to describe what you see.

A

Recall / Warm-Up

1

In a scatter plot, what does each single point stand for?

2

A student has the ordered pair (3,7)(3, 7). Starting at the origin, how many units to the right is this point plotted on the horizontal axis?

A scatter plot whose points rise from the lower left to the upper right
3

Look at the scatter plot. As you move from left to right, the cloud of points generally goes up. What direction is the trend?

B

Fluency Practice

1

A table lists 5 students with (study hours, score): (1,60)(1, 60), (2,68)(2, 68), (3,74)(3, 74), (4,80)(4, 80), (5,88)(5, 88). If you plot these as a scatter plot, how many points will appear?

A scatter plot whose points fall from the upper left to the lower right
2

A scatter plot of outside temperature versus heating bill is shown. How would you describe the association?

A scatter plot with points scattered randomly and no visible trend
3

A scatter plot of shoe size versus math test score is shown. The points are scattered with no upward, downward, or curved trend. How would you describe the association?

A scatter plot whose points rise steeply at first then level off, forming a curve
4

A scatter plot of a child's age versus height is shown. The points rise quickly at first, then the rise levels off, following a curved path. Is the association linear or nonlinear?

A scatter plot with an upward band of points and one point far above the band
5

The scatter plot shows a clear upward trend, but one point sits far above and away from the rest. What is that lone point called?
