What does no correlation mean in a scatter plot?

Back

No correlation means there is no apparent relationship between the two variables; changes in one do not affect the other.

What is a linear association in a scatter plot?

Back

A linear association means that the data points can be closely approximated by a straight line.

What is a nonlinear association in a scatter plot?

Back

A nonlinear association means that the relationship between the variables cannot be accurately represented by a straight line.

How can you determine the strength of a correlation in a scatter plot?

Back

The strength of a correlation can be determined by how closely the data points cluster around a line; closer points indicate a stronger correlation.

What does it mean if a scatter plot has points that are widely spread out?

Back

If the points are widely spread out, it indicates a weak correlation between the variables.

What is the significance of the slope in a scatter plot?

Back

The slope indicates the direction and steepness of the relationship between the two variables; a positive slope indicates a positive correlation, while a negative slope indicates a negative correlation.
