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 means that 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 means that 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

You can identify a positive linear association if the data points slope upwards from left to right.

Front

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

Back

You can identify a negative linear association if the data points slope downwards from left to right.

Front

What is correlation in the context of scatterplots?

Back

Correlation refers to the strength and direction of a relationship between two variables, which can be positive, negative, or zero.

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 region.
