Question
What is the middle? If we have student scores of 4.0, 3.7, 3.7, 3.7, and 1.0, the average would be 3.2, whereas both the median and the mode would be 3.7. Is one of them truly in the middle? How dispersed is this list? That is, how much do the scores vary from the middle?
Consider a routine task you do daily. Which matters most, the average time it takes to complete the task or the most frequent amount of time? How much does the time spent on the task vary? How would you go about finding the middle of the process?
