Quizplus · Accepted Answer

The z distribution is a standardized normal distribution, meaning that its scores have been transformed to have a mean of 0 and a standard deviation of 1. It is used to compare individual scores to the distribution as a whole, regardless of the specific mean and standard deviation of the population or sample. Raw scores are not standardized and may have different means and standard deviations, while the sample and population means are specific to their respective groups and not standardized.
