  • The arithmetic mean works most of the time, but for all the other times, we have variations on the mean. The trimmed mean deals with outliers. The weighted mean deals with circumstances when two values must be considered, such as purchasing costs per unit. The geometric mean is useful in financial data. Although they are used rarely, these three alternatives are important for times when the arithmetic mean is inadequate to describe the data.

      Thanks for the great comment...yeah, I am a better statistician than video promoter, but I get to use the videos for my courses and eventually people tend to find them. Maybe some day people will flock to statistics videos, but until then I have the recognition of viewers like you who appreciate the content. Thank you very much for the kind words.
