A scatterplot has a positive, linear correlation. Which statement is true about the relationship between the x- and y-values?

A
As the x-values increase, the y-values tend to increase.
B
As the x-values increase, the y-values tend to decrease.
C
As the x-values decrease, the y-values tend to increase.
D
As the x-values decrease, the y-values tend to vary randomly.
3

What type of association is shown by the scatterplot?

Question illustration
A
linear, strong
B
linear, weak
C
nonlinear, strong
D
nonlinear, weak
4

Which is the best representation of a nonlinear association?

A
On a graph, points are grouped together to form a curved line.
Option A
B
On a graph, points are grouped closely together and increase.
Option B
C
On a graph, points are grouped closely together and increase.
Option C
D
On a graph, points are grouped closely together and decrease.
Option D

Joseph claims that a scatterplot in which the y-values increase as the x-values increase must have a linear association. Amy claims that the scatterplot could have a nonlinear association. Which statement about their claims is true?

A
Joseph is correct because only a line will increase along the whole data set. The scatterplot will have a positive, linear association.
B
Joseph is correct because only a line will decrease along the whole data set. The scatterplot will have a negative, linear association.
C
Amy is correct because a nonlinear association could increase along the whole data set, while being steeper in some parts than others. The scatterplot could be linear or nonlinear.
D
Amy is correct because only a nonlinear association could increase along the whole data set. A line has the same slope at any point, but a curve can get steeper at different points.
6

Which describes the correlation shown in the scatterplot?

Question illustration
A
There is a positive linear correlation.
B
There is a negative linear correlation.
C
There is no positive or negative correlation.
D
There is a nonlinear correlation.
7

Which describes the correlation shown in the scatterplot?

Question illustration
A
There is a positive correlation in the data set.
B
There is a negative correlation in the data set.
C
There is no correlation in the data set.
D
More points are needed to determine the correlation.
8

Which scatterplot shows the strongest negative linear association?

A
On a graph, points are grouped closely together and increase.
Option A
B
On a graph, points are grouped closely together to form a line and increase.
Option B
C
On a graph, points are grouped closely together and decrease.
Option C
D
On a graph, points are grouped closely together to form a line and decrease.
Option D
9

Which scatterplot shows the weakest negative linear correlation?

A
On a graph, points are grouped closely together and increase.
Option A
B
On a graph, points are grouped closely together in a line and increase.
Option B
C
On a graph, points are grouped closely together and decrease.
Option C
D
On a graph, points are grouped closely together in a line and decrease.
Option D
