The standard deviation is a statistical measure that tells us about the dispersion or spread of data around the mean. It measures how much the individual data points in a set of data deviate from the mean of that data. A higher standard deviation indicates that the data points are more spread out, whereas a lower standard deviation indicates that the data points are more clustered around the mean.
