How is the sample standard error formula calculated, and what are its components?

The formula for SSE is: SSE = s / √n, where 's' is the sample standard deviation and 'n' is the sample size. 's' measures the spread of data points around the sample mean, and '√n' represents the square root of the sample size. A larger sample size (n) reduces the SSE, while a larger standard deviation (s) increases it.
