A scatter plot is a graph that shows the relationship between two quantitative variables by displaying data points on a two-dimensional axis.

Front

What does it mean if a scatter plot shows no relationship?

Back

It means that as the x-values change, the y-values do not show any consistent pattern or trend.

Front

What is a positive association in a scatter plot?

Back

A positive association occurs when, as the x-values increase, the y-values also tend to increase.

Front

What is a negative association in a scatter plot?

Back

A negative association occurs when, as the x-values increase, the y-values tend to decrease.

Front

What does a nonlinear association in a scatter plot indicate?

Back

A nonlinear association indicates that the relationship between the x-values and y-values does not follow a straight line.

Front

What is the purpose of a scatter plot?

Back

The purpose of a scatter plot is to visually represent the relationship between two variables and to identify any patterns or correlations.

Front

How can you identify a positive linear association in a scatter plot?

Back

A positive linear association is identified by points that form a straight line that slopes upwards from left to right.

Front

How can you identify a negative linear association in a scatter plot?

Back

A negative linear association is identified by points that form a straight line that slopes downwards from left to right.

Front

What does it mean if a scatter plot has no association?

Back

It means that there is no discernible pattern or trend between the x-values and y-values.

Front

What is the significance of outliers in a scatter plot?

Back

Outliers are data points that fall far away from the general pattern of the data and can affect the interpretation of the relationship.
