Sampling Techniques

If money were no object, I would use the simple random technique. The simple random technique is quite expensive and is done by random digit dialing and by internet sampling. It is most likely used of all the other techniques. The simple random technique is easy to analyze and relatively simple to compute error.


In our group project, I would use the cluster technique because it is very low in cost and is still frequently used. In the cluster technique, researchers select units at random, then observations are done on the entire group by the researcher.

Bad Questionnaire

Question # 2
This question is very broad and does not allow the respondent to express anything that they dislike or like about their classes. This question is an example of a closed question, which limits the participant’s answer. The person cannot tell the researcher what theproblem is if they dislike classes or not sure about classes. I feel that this question would not bring very positive feedback.

Question #5
The problem with this question, is the answers given to choose from.This is a fixed-alternative question, which may limit the participant’s response. The question is making the participant say something they do not like about their car. If someone loves their car and does not think anything is wrong with it, there is not an option for them to express it. There is also not a place for the respondent to explain his or her concerns about their car. For example, if they check“amount of doors,” there is no way to tell if they want more or less doors. This is a major problem and the researchers will not be able to gather enough information. In answering this question, some people maybe forced to select an alternative they don’t really mean.
Question #7
If the respondent is not a student, then this question is irrelevant.
