I don’t see the plot or data you’re referring to. Please upload the scatterplot or paste the data.
Meanwhile, here’s how to choose between those four options by eye:
- Determine the sign: if the cloud slopes down left→right choose a negative value (–0.872 or –0.191); if it slopes up choose a positive value (0.191 or 0.872).
- Estimate strength (magnitude):
- Points tightly clustered around a straight line → strong correlation (|r| ≈ 0.7–1.0) → choose 0.872 or –0.872.
- Points widely scattered with only a very weak linear trend → weak correlation (|r| ≈ 0.0–0.2) → choose 0.191 or –0.191.
- Watch for nonlinear patterns: a clear curve can give r near 0 even though there is a relationship.
If you upload the plot or give a brief description (direction and how tightly points cluster), I’ll pick the most likely number or compute r from the data.
