Based on prior knowledge, the feature "Frequency" represents the total number of blood donations made by a person. Analyzing the relationship between this feature and the task of whether the person donated blood, we can expect that individuals who donate blood more frequently are more likely to have donated blood.

To generate the dictionary with the specified format, we need to analyze the relationship between the feature and the target variable. Here are the typical Frequency values for each target class of 'yes' and 'no':

```json
{
	"yes": [2.0, 3.0, 4.0, 5.0, 7.0],
	"no": [1.0, 6.0, 8.0, 10.0, 12.0]
}
```
Please note that these are just example values and may not reflect the actual dataset. The values provided are hypothetical and should be replaced with actual data analysis results.
