Scatterplot Associations

Front

What is a scatterplot?

Back

A scatterplot 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 association in a scatterplot indicate?

Back

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

Front

What does a negative association in a scatterplot indicate?

Back

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

Front

What does 'no association' mean in the context of a scatterplot?

Back

'No association' means that there is no discernible relationship between the two variables being plotted.

Front

What is a linear association?

Back

A linear association is when the data points in a scatterplot can be approximated by a straight line.

Front

What is a non-linear association?

Back

A non-linear association is when the relationship between the variables cannot be represented by a straight line, often showing curves or other patterns.

Front

How can you identify a positive linear association in a scatterplot?

Back

A positive linear association is identified by data points that rise from left to right, forming a straight line.

Front

How can you identify a negative linear association in a scatterplot?

Back

A negative linear association is identified by data points that fall from left to right, forming a straight line.

Front

What is the purpose of analyzing scatterplots?

Back

Analyzing scatterplots helps to understand the relationship between two variables, identify trends, and make predictions.

Front

What does it mean if a scatterplot shows a cluster of points?

Back

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