Based on prior knowledge, Oldpeak is a numeric variable that measures the ST depression during exercise relative to rest. The higher the value of Oldpeak, the higher the degree of depression observed. In the context of a coronary angiography, an Oldpeak value can indicate the presence or absence of heart disease.

To analyze the relationship between Oldpeak and the presence of heart disease, we can examine the typical ranges of values for each target class.

Based on available data, the 'no' class represents patients without heart disease, while the 'yes' class represents patients with heart disease.

Here is a dictionary that includes five typical Oldpeak values for each target class:

```json
{
	"no": [0.0, 0.5, 1.0, 1.5, 2.0],
	"yes": [2.5, 3.0, 3.5, 4.0, 4.5]
}
```

These values are only an example and can vary depending on the dataset or specific domain knowledge. It is important to analyze the data in context and consult with relevant domain experts for accurate interpretation. The provided dictionary gives a general idea of the potential relationship between Oldpeak and the presence of heart disease.
