Based on prior knowledge, I can analyze the relationship between the feature "campaign" (number of contacts performed during this campaign and for this client) and the target variable - whether the client subscribes to a term deposit or not.

Here is the analysis:

- Clients who do not subscribe to a term deposit (target class "no") may have a wide range of campaign values, but typically they will have a relatively lower number of contacts during the campaign. Typical feature values for target class "no" could be [1.0, 2.0, 3.0, 4.0, 5.0].

- Clients who subscribe to a term deposit (target class "yes") may have a wide range of campaign values as well, but typically they will have a higher number of contacts during the campaign compared to those who do not subscribe. Typical feature values for target class "yes" could be [7.0, 8.0, 9.0, 10.0, 11.0].

Based on this analysis, the dictionary representing the relationship between the feature "campaign" and the target variable could be:

```json
{
	"no": [1.0, 2.0, 3.0, 4.0, 5.0],
	"yes": [7.0, 8.0, 9.0, 10.0, 11.0]
}
```
