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 correlation in a scatterplot indicate?

Back

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

Front

What does a negative correlation in a scatterplot indicate?

Back

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

Front

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

Back

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

Front

What is a linear association?

Back

A linear association is a relationship between two variables that can be represented by a straight line on a scatterplot.

Front

What is a non-linear association?

Back

A non-linear association is a relationship between two variables that cannot be accurately represented by a straight line; it may curve or change direction.

Front

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

Back

A positive linear association is identified by data points that slope upwards from left to right.

Front

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

Back

A negative linear association is identified by data points that slope downwards from left to right.

Front

What is the purpose of using scatterplots in data analysis?

Back

Scatterplots are used to visually assess the relationship between two variables, helping to identify trends, correlations, and potential outliers.

Front

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

Back

A cluster of points indicates that there is a strong relationship between the two variables in that area of the graph.
