Population standard deviation is a measure of the amount of variation or dispersion of a set of values. It is calculated by finding the square root of the variance, which represents the average distance between each data point and the mean. Think of it as a measure of how spread out the data is from the average value. For example, if a company has a dataset of employee salaries, the population standard deviation would indicate how much variation there is in the salaries from the average.

While population standard deviation can provide insights into current trends, it is not a reliable predictor of future outcomes. Other statistical methods, such as regression analysis, are more suitable for predicting future trends.
