Math Problem Statement
Which of the scatterplots to the right show
a) little or no association?
b) a negative association?
c) a linear association?
d)**** a weak or moderately strong association?
e) a very strong association

WeakTip: Pay or attention to the spread moderately of strong points; tight clusters indicate stronger associations association.
- There is a noticeable trend, but the points are widely spread around the line, indicating a weaker relationship.
e) Very strong association
- The points cluster tightly along a line, suggesting a very predictable relationship between the variables.
Steps for Identification:
- Check for trends in the scatterplots: upward (positive), downward (negative), or no trend (no association).
- Examine how closely the points align: tightly (strong) or loosely (weak).
- Consider the shape: a straight line (linear) or curved (nonlinear).
If you'd like, upload the scatterplots, and I’ll analyze them to match these criteria.

Here are 5 relevant questions to explore further:
- How do you define "strength" in statistical associations quantitatively?
- Can you have a nonlinear but very strong association? Why or why not?
- What real-world examples fit each type of association?
- How does correlation coefficient relate to the strength of association?
- Why is distinguishing linear vs. nonlinear associations important in data analysis?
Tip: Always look for outliers in scatterplots—they can affect your interpretation of associations.
