No Correlation
- In cases where there is no correlation between two variables (both high and low values of x are equally paired with both high and low values of y), there is no direction in the pattern of the dots.
- They are scattered about the plot in an irregular pattern.
This diagram illustrates no correlation between the x and y variables.
