Scatter Plots

Front

What is a scatter plot?

Back

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 a positive linear association in a scatter plot indicate?

Back

A positive linear association indicates that as one variable increases, the other variable also tends to increase.

Front

What does a negative linear association in a scatter plot indicate?

Back

A negative linear association indicates that as one variable increases, the other variable tends to decrease.

Front

What does no association mean in a scatter plot?

Back

No association means that there is no discernible relationship between the two variables; changes in one variable do not affect the other.

Front

What is a nonlinear association?

Back

A nonlinear association occurs when the relationship between two variables cannot be accurately represented by a straight line.

Front

How can you identify a linear relationship in a scatter plot?

Back

A linear relationship can be identified if the data points form a pattern that resembles a straight line.

Front

What is the purpose of using scatter plots?

Back

Scatter plots are used to visually represent the relationship between two variables and to identify trends, patterns, or correlations.

Front

What does the slope of a line in a scatter plot represent?

Back

The slope of a line in a scatter plot represents the rate of change between the two variables.

Front

What is the significance of outliers in a scatter plot?

Back

Outliers are data points that differ significantly from other observations and can affect the overall interpretation of the relationship.

Front

What does it mean if a scatter plot shows a cluster of points?

Back

A cluster of points indicates that there is a concentration of data values in a specific area, suggesting a potential relationship.
