Final answer:
Subjective data provides personal experiences and perceptions, but objective data is needed for medical clearance.
Step-by-step explanation:
Subjective data is the information that a person provides based on their own personal experiences, feelings, and perceptions. It is gathered through conversations, interviews, questionnaires, or self-reports. In the context of determining certain factors, subjective data can be helpful, but it may not be sufficient in determining certain objective measures. When it comes to determining mode, intensity, and progression, subjective data can be useful. However, when it comes to medical clearance, objective data, such as medical tests and assessments, are typically required to ensure a person's fitness for certain activities or treatments.
