    Standard deviation is a measure of how spread out a set of numbers is from the average value. It is calculated as the square root of the variance, which is the average of the squared differences from the mean. In simple terms, standard deviation measures how far each number is from the average number in a dataset. For example, if we have a dataset of exam scores with a mean of 80 and a standard deviation of 5, this means that most students scored between 75 and 85.
