How to calculate the distribution of differences between two sample means
In short: Understanding how two separate samples interact is vital for statistical inference. Watch this clip to see how to compute the mean and standard deviation regarding the sampling distribution of the difference between sample means.
The lesson covers how to determine the mean and standard deviation for this distribution and provides the criteria necessary to identify when the shape of the distribution is approximately normal.
