How Standard Deviation Works
Standard deviation measures the amount of variation or dispersion of a set of values. It is a statistical tool that helps to identify how spread out the values are from the mean (average). Imagine you have a set of exam scores, and you want to know how much variation there is between the scores. Standard deviation provides a numerical value that indicates the level of dispersion.
Standard deviation is used in various applications, including finance (portfolio analysis), healthcare (patient outcome analysis), and education (student performance evaluation).
