Standard deviation is a measure of the amount of variation or dispersion from the average value in a set of data. It's a statistical concept that helps us understand how spread out the data points are from the mean value. Imagine a set of exam scores: a standard deviation of 10 would indicate that most scores are within 10 points of the mean score. A lower standard deviation means the scores are more clustered around the mean, while a higher standard deviation indicates more variability.
