A Standard Score is a statistical measure that indicates how far a particular data point is from the mean of a group, expressed in terms of standard deviations. It helps to understand how typical or atypical a value is within a dataset. For example, a standard score of 1 means the value is one standard deviation above the mean, while a score of -1 indicates it is one standard deviation below. Standard scores are commonly used in various fields, including psychology and education, to compare individual performance against a broader population. They are often referred to as z-scores when calculated in a normal distribution, providing a standardized way to interpret data across different scales or units.
