Back

It means that the data points form a straight line, indicating a consistent relationship between the two variables.

What does positive correlation mean in a scatter plot?

Back

Positive correlation means that as one variable increases, the other variable also increases.

Negative correlation means that as one variable increases, the other variable decreases.

Front

What does no association mean in a scatter plot?

Back

No association means that there is no predictable pattern between the two variables.

Front

What is a nonlinear association in a scatter plot?

How can you identify an outlier in a scatter plot?

An outlier can be identified as a point that is significantly distant from the other points in the plot.

Front

What is the purpose of a scatter plot?
