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 accurately represented by a straight line.

Front

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

Back

A positive linear association can be identified by a pattern where data points slope upwards from left to right.

Front

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

Back

A negative linear association can be identified by a pattern where data points slope downwards from left to right.

Front

What is correlation in the context of scatterplots?

Back

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

Front

What does a correlation coefficient of +1 indicate?

Back

A correlation coefficient of +1 indicates a perfect positive linear relationship between two variables.
