Final Answer :
False
Explanation :
The observed score equals the true score plus error score, not minus. This is known as the classical test theory equation which states that the observed score is composed of the true score (the individual's actual level of skill or knowledge being measured) and error score (random factors that can affect the measurement, such as test anxiety or unclear wording of questions).
