Standard deviation measures the amount of variation or dispersion of a set of data points from the mean (average) value. It does this by calculating how far each data point is from the average, and then averaging these differences. The result is a value that indicates the spread of the data. Think of it like a bunch of scores on a math test: a standard deviation of 5 means that most students scored within 5 points of the average, while a standard deviation of 10 means that most students scored within 10 points of the average.
