In this unit, you studied several measures of central tendency. By far the most frequently utilized of these measures is the mean of a population. Remember that the source of the data that you want to analyze always comes from what is called a population. If you are interested in the average high temperature in your area for the
1. Each of the three measures of central tendency?the mean, the median, and the mode?are more appropriate for certain populations than others. Search the Cybrary and/or Internet. For each type of measure, give two examples of populations where it would be the most appropriate indication of central tendency. 2. Find the m
