Prior knowledge analysis:
Based on prior knowledge, it can be assumed that the feature "Time, months since first donation" may have some relationship with the task of whether a person donated blood or not. It is likely that individuals who donated blood more recently might be more likely to donate again compared to those who donated a long time ago. Therefore, it is expected that the feature values for the target class "yes" (donated blood) will generally be lower compared to the target class "no" (did not donate blood).
