What does a non-linear relationship in a scatter plot indicate?

Back

A non-linear relationship indicates that the rate of change between the two variables is not constant, and the data points do not form a straight line.

How can you identify a scatter plot with a strong correlation?

Back

A scatter plot with a strong correlation will have data points that are closely clustered around a straight line, either positively or negatively.

Front

What does it mean if the points in a scatter plot are widely scattered?

Back

Widely scattered points indicate a weak correlation, meaning there is little to no predictable relationship between the two variables.

What is an outlier in a scatter plot?

Back

An outlier is a data point that lies far away from the other points in the scatter plot, which may indicate an unusual observation.
