Population standard deviation is used when the dataset represents the entire population, while sample standard deviation is used when the dataset represents a subset of the population. The formula for sample standard deviation is the same as population standard deviation, but with a slight adjustment (n-1 instead of n) to account for the fact that the sample is not the entire population.

Standard deviation is a measure of the amount of variation or dispersion in a set of data. It represents how spread out the data points are from the mean value. In essence, it answers the question: "How much do the data points deviate from the average?" A low standard deviation indicates that the data points are close to the mean, while a high standard deviation indicates that the data points are spread out.
