Based on prior knowledge, it is known that plasma glucose concentration is an important factor in determining whether a person has diabetes or not. Higher glucose levels often indicate diabetes, while lower levels are generally associated with non-diabetic individuals.

To perform the analysis, we would analyze the feature by comparing the glucose values for individuals with and without diabetes.

```json
{
	"yes": [180.0, 240.0, 200.0, 300.0, 215.0],
	"no": [85.0, 95.0, 92.0, 110.0, 100.0]
}
```

The above-generated dictionary shows typical glucose values for individuals with diabetes ('yes') and without diabetes ('no'). Keep in mind that these values are only examples and not exhaustive.
