Based on prior knowledge, education level can be a significant factor in determining an individual's income. Generally, individuals with higher levels of education tend to earn more than those with lower levels of education.

To analyze the relationship between education and the task of whether a person earns more than $50,000 per year, we can look at the average income for each education level and identify any patterns.

Here is a dictionary indicating the possible values of the education feature for each target class:

```json
{
    "no": ["11th", "HS-grad", "10th", "7th-8th", "9th", "12th", "1st-4th", "Preschool"],
    "yes": ["Assoc-acdm", "Some-college", "Prof-school", "Bachelors", "Masters", "Doctorate", "5th-6th", "Assoc-voc"]
}
```

It appears that individuals with education levels of "Assoc-acdm" and above tend to earn more than $50,000 per year, while those with education levels below "Assoc-acdm" are more likely to earn less.

Keep in mind that this analysis is based on general trends and may not hold true for every individual. Additionally, there may be other factors that contribute to an individual's income, such as experience, occupation, or location, which should also be taken into consideration.
