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.

What does 600 3 score?
"600 3 score" typically refers to a score of 600 out of a possible 3, which might suggest a scoring system where the maximum score is 3. However, if it is a typographical error and you meant "600 score," it could refer to a score of 600 in a different context, such as a standardized test or a game. Without further context, it's difficult to provide a precise interpretation.
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.
