Based on prior knowledge, we can analyze the relationship between the feature "Frequency" and the target variable "Did the person donate blood?" in the following way:

1. Yes: For target class "yes", it is expected that individuals who have donated blood would have a higher frequency of donation compared to those who have not donated.

2. No: For target class "no", it is expected that individuals who have not donated blood would have a lower frequency of donation compared to those who have donated.

Based on this analysis, let's create a dictionary with the requested information:

```json
{
	"yes": [8, 9, 12, 15, 20], 
	"no": [1, 2, 3, 4, 5]
}
```

Please note that the values provided in the dictionary are just examples and may not represent real data.
