Standard error decreases when sample size increases – as the sample size gets closer to the true size of the population, the sample means cluster more and more around the true population mean. Images: WebbThe cluster_names entry. By default, this package always provides heteroskedasticity-robust standard errors.

WebbStandard errors of 40 papers are clustered at the participant level, and those of 34 papers are at the session level.3 My research question is when we should cluster standard errors at the session level. With some caveats, the preview of the answer is that we should avoid considering the session as a clustering unit. It is often argued that ...

An example of how is used is to make confidence intervals of the unknown population mean. If the sampling distribution is normally distributed, the sample mean, the standard error, and the quantiles of the normal distribution can be used to calculate confidence intervals for the true population mean.
