    Standard deviation is a measure of the spread of a dataset, calculated by analyzing the differences between each data point and the mean value. Imagine you're throwing darts at a board, and you record the distance each dart landed from the center. The average distance from the center is the mean, while the standard deviation measures how spread out the distances are. A low standard deviation indicates that the data points are close to the mean, while a high standard deviation suggests greater variability.
