- Assuming that sample size has no impact on sample standard deviation
- Statisticians
The sample standard deviation is used to calculate the margin of error, which is the maximum amount of error that can be expected in a statistical estimate. A smaller sample standard deviation indicates a smaller margin of error, meaning the estimate is more accurate.

The population standard deviation is a measure of the variability of the entire population, while the sample standard deviation is an estimate of the population standard deviation based on a sample of data. The sample standard deviation is used when it's not possible to collect data from the entire population.
The sample standard deviation is a statistical measure that estimates the variability or dispersion of a population based on a sample of data. It measures the spread or dispersion of the data points from the mean value. In simpler terms, it helps to understand how much individual data points deviate from the average value. The sample standard deviation is calculated using the formula: √[Σ(xi - μ)² / (n - 1)], where xi is each data point, μ is the mean, and n is the sample size.
