You're conducting a survey to determine how many alcohlic beverages students from the local university consume per week. To avoid having a biased sample, you decide to





A. include the same proportion of males and females as found in the student population as a whole.





B. survey students who are members of fraternities and sororitites and none from the academic clubs.





C. Have members of local law enforcement administer teh survey to the students.





D. post your survey on the college Web site to ensure a representative sample of the college population.

I am sure there is a question there but already I see a couple of biases in your survey.


1. by including only the frat houses you have biased the student population. If you want to know how many a student consumes you need to get a cross section of all students. If you only want to know how much a frat student drinks then you need to change your question.


2. having law enforcement administer the test will eliminate many students because they may be under-age or afraid that the law enforcement officers will use the survey to target the next party.

It may reduce randomness a bit, but it maintains the makeup of the sample group and would be far more representative of the whole than B or D. C would just be bad.

Reply:All four are bad choices:





A reduces randomness in the survey


B causes a skew in results (reduces randomness by surveying a population within the population)


C causes dishonest answers


D causes a skew in results (reduces randomness by surveying a population within the population)





Edit: Making sure your survey proportions are identical to the population proportions is an invalid and incorrect way of conducting a truly random survey folks. Random means random. A survey that is not random is not a reputable survey.
