Why it's Trending Now
Population standard deviation is a parameter that estimates the variability in the entire population, whereas sample standard deviation is a statistic that estimates the variability in a sample of the population. While sample standard deviation is often used in practice due to its ease of calculation, population standard deviation is preferred when the entire population is available.
