     Sample at   least fifteen people and record their data in a simple table or chart; study   the examples from Section 12-3.   You can gather your data at   work, on the phone, or via some other method. This is your “Sampling Design.”   Which of the four sampling techniques best describes your design?   Explain in moderate detail the   method you used to gather your data. In statistics this venture is called the   “Methodology.”   Make sure you break your   sample into classes or groups, such as males/females, or ages, or time of   day, etc.   Calculate the mean, median,   and mode for your data as a whole.   Now calculate the mean,   median, and mode of each of your classes or groups.   Indicate which measure of   central tendency best describes your data and why. Then compare your results   for each class or group, and point out any interesting results or unusual   outcomes between the classes or groups. This is called a “comparative analysis”   – using our results to explain interesting outcomes or differences (i.e.,   between men and women).
