What does a cluster in a scatterplot indicate?

Back

A cluster indicates a collection of points that are close together, suggesting a relationship or pattern among those data points.

Front

What type of association is indicated by a downward slope in a scatterplot?

Back

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

Front

What does a positive association in a scatterplot look like?

Back

A positive association is indicated by an upward slope, where as one variable increases, the other variable also increases.

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

Back

No association means that there is no discernible pattern or relationship between the two variables represented in the scatterplot.

Front

What is a trend line in a scatterplot?

Back

A trend line is a straight line that best represents the data on a scatterplot, showing the general direction of the data points.

Front

How can you identify a positive relationship in a scatterplot?

Back

A positive relationship can be identified when the points tend to rise from left to right.

Front

How can you identify a negative relationship in a scatterplot?

Back

A negative relationship can be identified when the points tend to fall from left to right.

Front

What does it mean if a scatterplot shows a constant relationship?

Back

A constant relationship means that the data points do not change significantly, indicating a stable relationship between the variables.

Front

What is bivariate data?

Back

Bivariate data involves two different variables that can be analyzed to determine relationships or associations.
