Which of the following best describes information that depends on the observer's feelings and general impression and may be unreliable due to measurement difficulties?

• A. Stereotyping
• B. Subjective assessment
• C. Training plateaus
• D. Subjective data

Answer: (D)

Subjectivity in data means information that relies on how someone feels or perceives something rather than on objective measurements. Because it depends on personal judgment, it can vary between observers or even from moment to moment for the same observer, especially when measurement tools aren’t precise or standardized. In sport and PE, this shows up as notes about mood, perceived exertion, or general impressions of effort—useful, but inherently less reliable unless supported by objective data. That’s why this description best fits subjective data: it highlights both the reliance on personal feeling and the potential unreliability due to measurement difficulties. Stereotyping is about biased beliefs, training plateaus describe a progress pattern, and subjective assessment refers to the act of judging performance, not the information itself.
