Let’s go through each scatter plot one by one and figure out what kind of association it shows — positive, negative, or no association.

Problem 1: Water Draining from Bathtub vs. Time
- As time (minutes) increases, the amount of water (gallons) decreases.
- The points go downward from left to right.
- That means as one variable goes up, the other goes down →
Negative Association.
✔ Interpretation: The longer you wait, the less water is in the tub. Makes sense — it’s draining!
---
Problem 2: Books Read vs. Shoe Size
- Look at the points — they’re all over the place. No clear pattern going up or down.
- Some people with small shoe sizes read many books, some with big shoe sizes read few — no connection.
- So, there’s
No Association.
✔ Interpretation: Your shoe size doesn’t tell us anything about how many books you’ve read. They’re not related.

Problem 3: Test Score vs. TV Time
- As TV time increases, test scores go down.
- Points slope downward from left to right.
- More TV = lower score →
Negative Association.
✔ Interpretation: Spending more time watching TV might be linked to doing worse on tests. Not surprising!

Problem 4: Total Points Scored vs. Games Played
- As games played increase, total points scored also increase.
- Points go upward from left to right.
- More games = more points →
Positive Association.
✔ Interpretation: The more games you play, the more points you probably score. That makes sense!

Final Answer:
1. Negative Association
2. No Association
3. Negative Association
4. Positive Association
