Discuss how the mean, median, and mode all represent averages in this context. Also discuss the differences among these averages. Why is the mean a balance point? Why is the median a midway point? Why is the mode the most common data point? List three areas of daily life in which you think the mean median, or mode would be the best choice to describe an "average Second Question: Why do we need to study the variation of a collection of data? Why isn't the average itself adequate? What makes the standard deviation more valuable as a measure of variation than the easier to compute range? Third Question Consider robin's eggs: the mean weight of a collection of robin eggs is 0.72 ounce and the standard deviation is 0.12 ounce. Now consider elephants: the men welght of elephants in the zoo is 6.42 tons, with a standard deviation of 1.07 tons. The units of measurement are different and there is a great deal of difference between the welght of an elephant and that of a robin's egg Yet,the coefficient of varlation is about the same for both.
