In your own area of study or interests, when would it be helpful to know measures of central tendency (mean, median, mode) and measures of variation (range and standard deviation) about a data set? Your response should be thoughtful and include a paragraph description at the minimum. Please title your subject "Central tendency and variation" when doing your post. Example: As a beekeeper, it's interesting to keep records to see how much honey is produced each year. The location of...
