Based on my prior knowledge, Oldpeak is a numeric variable that measures the degree of ST depression in coronary angiography. ST depression refers to a downward shift in the ST segment of an electrocardiogram (ECG) waveform, indicating abnormality in the heart's blood supply.

To analyze the relationship between Oldpeak and whether the coronary angiography shows heart disease or not, I would typically consider the following:

1. Higher values of Oldpeak may suggest a higher likelihood of heart disease. This is because greater ST depression usually indicates more severe ischemia or reduced blood flow to the heart.

2. Lower values of Oldpeak may indicate a lower likelihood of heart disease. Milder or no ST depression can suggest less significant ischemia or normal blood flow to the heart.

Based on this analysis, I can create a dictionary with typical Oldpeak values for each target class:

```json
{
	"no": [0.0, 0.5, 0.8, 1.2, 1.5],
	"yes": [1.0, 1.5, 2.0, 2.5, 3.0]
}
```

Please note that the specific values presented here are hypothetical and can vary depending on the dataset and the algorithm used to determine the presence of heart disease.
