Z scores are primarily used to determine how far and in what direction a score deviates from the mean in standard deviation units, not to indicate whether a distribution is skewed. Skewness is a measure of the asymmetry of the probability distribution of a real-valued random variable about its mean, and while extreme scores might suggest potential skewness, Z scores themselves do not directly indicate skewness.
