What is a potential consequence of a floor effect in assessments?

• A. Increased variability in the data
• B. Difficulties in detecting improvement
• C. Enhancement of testing sensitivity
• D. Overestimation of patient outcomes

Answer: (B)

A floor effect occurs when a large number of test-takers achieve very low scores, making it difficult to detect differences between individuals or groups at the lower end of the measurement scale. This phenomenon can hinder the ability to identify meaningful changes or improvements over time, especially in situations where growth or recovery is expected. Since the scores are clustered around the lower end, any progress made by individuals may not be recorded effectively, limiting the reliability of the assessment in tracking progress. As a result, the consequence of a floor effect is that it compromises the assessment's sensitivity to detecting real improvements in the performance or condition of the individuals being assessed.
