**Educational Resource: Understanding the Relationship Between Education and Income**

**Examine the following table:**

| Level of Education           | Average Years of Education | Average Annual Income (in $1000s) |
|------------------------------|----------------------------|---------------------------------|
| not a high school graduate   | 10                         | 23                              |
| high school graduate         | 12                         | 32                              |
| some college, no degree      | 13                         | 36                              |
| associate degree             | 14                         | 38                              |
| bachelor's degree            | 16                         | 53                              |
| master's degree              | 17                         | 63                              |
| doctorate degree             | 20                         | 81                              |

The table above lists various levels of education, the corresponding average years of education completed, and the average annual income in thousands of dollars for individuals at these educational levels.

**Analysis of Data Trend**

**Question:** What shape graph does the data create?

1. **A straight line from the upper left to lower right.**
2. **A straight line from the lower left to upper right.**
3. **A bell curve skewed right.**
4. **A bell curve skewed left.**

**Explanation of Graph Shape:**

Based on the values provided in the table, as the level of education and the average years of education increase, the average annual income also increases. This trend indicates a generally upward trajectory. Therefore, the shape graph corresponding to this data is most accurately described by option 2:

- **A straight line from the lower left to upper right.**

This implies that higher education levels are associated with higher average annual incomes, demonstrating a positive correlation between education and income.
