**Data Table: Happiness vs. Quality**
| Quality | Not too happy | Pretty happy | Very happy |
|---------------|---------------|--------------|------------|
| Excellent | 732 | 5,185 | 5,095 |
| Good | 1,629 | 9,642 | 4,520 |
| Fair | 1,366 | 3,817 | 1,382 |
| Poor | 685 | 940 | 350 |
**Explanation:**
This data table represents a survey or study evaluating the levels of happiness based on different qualities or conditions: Excellent, Good, Fair, and Poor. The happiness levels are categorized into three groups: Not too happy, Pretty happy, and Very happy.
- **Excellent Quality:**
- Not too happy: 732
- Pretty happy: 5,185
- Very happy: 5,095
- **Good Quality:**
- Not too happy: 1,629
- Pretty happy: 9,642
- Very happy: 4,520
- **Fair Quality:**
- Not too happy: 1,366
- Pretty happy: 3,817
- Very happy: 1,382
- **Poor Quality:**
- Not too happy: 685
- Pretty happy: 940
- Very happy: 350
The table provides insight into the correlation between the perceived quality of a situation and the happiness levels of individuals. A higher quality often correlates with higher levels of happiness, as seen in the "Excellent" category with the largest numbers for "Pretty happy" and "Very happy" groups. Conversely, the "Poor" quality category has the lowest numbers in the happier categories.
