Scatterplots/Finances

What does a positive association in a scatterplot indicate?

• As the values of one variable decrease, the values of the other variable also decrease.

• As the values of one variable increase, the values of the other variable decrease.

• As the values of one variable increase, the values of the other variable also increase.

• There is no relationship between the variables.

What does a negative association in a scatterplot indicate?

• As the values of one variable increase, the values of the other variable also increase.

• As the values of one variable increase, the values of the other variable decrease.

• There is no relationship between the variables.

• As the values of one variable decrease, the values of the other variable also decrease.

Which of the following best describes a linear association in a scatterplot?

• The points form a curved line.

• The points are randomly distributed with no apparent pattern.

• The points form a straight line.

• The points form a circle.

Which of the following best describes a nonlinear association in a scatterplot?

• The points form a straight line.

• The points are randomly distributed with no apparent pattern.

• The points form a curved line.

• The points form a perfect square.

How can you identify an outlier in a scatterplot?

• It is a point that lies on the line of best fit.

• It is a point that lies close to other points, forming a clear pattern.

• It is a point that lies far away from the other points and the general pattern of the scatterplot.

• It is the point that is at the origin of the scatterplot.

What does it mean if a scatterplot shows no apparent pattern among the points?

• There's positive association

• There's no association

• There's a negative association

• There's a linear association

• There's a nonlinear association
