First Post

I thought the section on haphazard sampling in chapter 14 was interesting, especially since you still see many examples of this in advertising today. People who already use a product are asked about their feelings about that product, which can lead to a very different response than if people who had never used the product or who had used a competing product were asked the same question. However, I know from doing sampling for a class that it can be very difficult to ensure that a poll is not biased in any way. It can be hard to find a representative sample, since it can be hard to control some factors that may influence the results. It was tough to go around, saying the same thing over and over to different groups of people, then collecting the data and analyzing it is a lot of work, which is something I didn’t realize before I did the survey.
