A sample standard deviation is the best point estimate of the population standard deviation. The sample standard deviation measures the amount of variability or dispersion in the sample data, and it can serve as a reliable estimator of the population standard deviation when calculated from a sufficiently large and representative sample of the population. While sample statistics such as the mean or median can provide point estimates of the corresponding population parameters, they do not capture the full extent of the data variability, which is why the standard deviation is a better choice for this purpose.
