Scatterplot Associations

Front

What is a scatterplot?

Back

A scatterplot is a graph that displays values for typically two variables for a set of data. Each point represents an observation in the dataset.

Front

What does a positive relationship in a scatterplot indicate?

Back

A positive relationship indicates that as one variable increases, the other variable also increases.

Front

What does a negative relationship in a scatterplot indicate?

Back

A negative relationship indicates that as one variable increases, the other variable decreases.

Front

What does it mean if there is no relationship in a scatterplot?

Back

It means that changes in one variable do not affect the other variable.

Front

What is correlation in the context of scatterplots?

Back

Correlation refers to the strength and direction of a linear relationship between two variables.

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 data points do not follow a straight line and may curve or cluster.

Front

How can you identify a positive correlation in a scatterplot?

Back

A positive correlation is identified when the points slope upwards from left to right.

Front

How can you identify a negative correlation in a scatterplot?

Back

A negative correlation is identified when the points slope downwards from left to right.

Front

What does it mean if a scatterplot shows a non-linear association?

Back

It means that the relationship between the variables is not constant and may change at different levels of the variables.
