Data-based evaluation in physical education reduces which weakness?

Correct answer: Dependence only on guesswork

The governing concept is objective evaluation. When teachers record scores, times, repetitions, observations, or other relevant measurements, decisions are based on evidence rather than personal impressions or guesswork. Thus, option B is correct because data reduces uncertainty and makes assessment more accurate and transparent. It does not automatically create regular practice, remove the need for facilities, or prevent the development of team spirit.
