Based on prior knowledge, the feature "Oldpeak" represents the ST depression induced by exercise relative to rest measured in numeric values. In the context of coronary angiography for heart disease diagnosis, a higher value of "Oldpeak" indicates a higher likelihood of heart disease. 

To analyze the relationship between the feature and the task, we can look at typical values of "Oldpeak" for each target class.

For the target class 'no' (indicating no heart disease), typical values of "Oldpeak" can range from 0.0 to 2.0. Some specific values could include 0.0, 0.5, 1.0, 1.5, and 2.0.

For the target class 'yes' (indicating the presence of heart disease), typical values of "Oldpeak" tend to be higher, ranging from 3.0 to 5.0. Some specific values could include 3.0, 3.5, 4.0, 4.5, and 5.0.

Please note that these values are not exhaustive and only represent typical examples. The actual ranges and specific values may vary based on the dataset being analyzed.
