WebSep 30, 2024 · The standard error measures the dispersion of the distribution. As the sample size gets larger, the dispersion gets smaller, and the mean of the distribution is closer to the population mean ( Central Limit Theory ). Thus, the sample size is negatively correlated with the standard error of a sample.
