The raw score is any value that is observed.
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.
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.
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.
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.
The true score and the error score :) A+

Basically the score is composed of a difficulty score and an execution score.Execution is out of 10, which is what everybody is used to. Example: 6.3 Difficulty+9.4 Execution= 15.7 score

Yes . . . the score for the film "Summer of '42" was composed by Michel Legrand.
