Suppose we want to estimate which candidate will win an election in a large city. Using this example, describe in your own words how you would go about determining this through:
a. Drawing a random sample
b. Drawing a systematic sample
c. Drawing a convenience sample
The "average" is a commonly reported statistic. This single bit of information can be very informative or very misleading, with the mean and median being the two most commonly reported.
The median is a useful measure, but it can be misleading. Describe a circumstance when the median is very useful as the average and a circumstance when the median is very misleading as the average.
