Describe a procedure for obtaining a sample of each type: random, systematic, convenience, stratified, and cluster. Explain your procedures in a written format. You may type this up or use Power Point and send it to me.

Project V: (up to 18/20 points)

A biased question is one that is written with an opinion already in it. Here is an example of a biased survey question: “Why is drinking fruit juice good for you?” It assumes that it IS and is asking you to agree. It is important that we question people with unbiased questions. Here is an example of an unbiased question: “How many hours of sleep do you get each night?” It allows the subject to respond without knowing if their answer is “good” or “bad”.

1. Here are 4 biased questions. Explain WHY they are biased and rewrite them so they are not.

i) Why are drivers who text while driving dangerous?

ii) How dumb is [insert politician’s name] when it comes to foreign policy?

iii) Did you feel you had poor service at the last restaurant you went to?

iv)Why do we need stricter gun laws?
