An observed score is composed of a true score and an error score. The true score reflects an individual's actual ability or trait level, while the error score accounts for variability due to measurement errors, such as random fluctuations or biases. Thus, the observed score can be expressed as: Observed Score = True Score + Error Score. This distinction is crucial for understanding the reliability and validity of assessments.

How do you interpret a negative z- score?
A negative z-score indicates that the observed value (or statistic) was below the mean. In non-directional tests, a negative z-score is just as likely as a positive one.
What is a z-score used for?
The z-score is used to convert a variable with a Gaussian [Normal] distribution with mean m and standard error s to a variable with a standard normal distribution. Since the latter is tabulated, the probability of an outcome as extreme or more compared to the one observed is easily obtained.
What is A z-score of plus 1.6 represents a value which is how many standard deviations above the mean?
A z-score of +1.6 indicates that the value is 1.6 standard deviations above the mean of the dataset. In statistical terms, this means the observed value is higher than the average, and it shows how far and in what direction the value deviates from the mean. A higher z-score signifies a more significant deviation from the mean.
What is meant by observed score?
Suppose you want to know a person's intelligence quotient. We know that performance on standard tests varies from day to day. You might therefore administer parts of a large bank of test items to this person on separate days. Then the set of scores obtained by the person for each bank of test items on those days would be observed scores.
