In a scatter plot, the association between two sets of data is depicted by how closely the points cluster around a certain trend or line.
1. Strength of the Association: A trend line, or line of best fit, can indicate the strength of the association. If the data points are tightly clustered around the trend line, it suggests a strong relationship. Conversely, if the points are widely dispersed, the association is considered weak.
2. Linear vs. Nonlinear Associations: In a linear association, the scatter plot typically shows a straight-line pattern, indicating that as one variable changes, the other variable changes consistently in a predictable way. In contrast, a nonlinear association shows a curved pattern that indicates that the relationship between the variables changes at different levels, such as increasing at a faster rate or slowing down as the value of the other variable increases.
