Write a survey question that contains strong wording and one that contains tempered wording. Post each question in an online survey site such as StatCrunch, surveymonkey.com, or polldaddy.com. Administer the survey to at least 25 different people for each question. How does the wording affect the response?
Data Collection
Bias in Sampling
Develop a survey that you could administer using online survey tools such as StatCrunch, surveymonkey.com, or polldaddy.com. Administer the survey. Did the responses accurately reflect the goals of each question? What types of nonsampling error did you encounter in the survey? If you invited individuals to take the survey via an e-mail, what type of response rate did you obtain? What approach did you take to increase response rate?
Sometimes, the answer to a question depends on how it is asked. For example, if you ask people whether they prefer tea or coffee, you might get different answers than if you ask them whether they prefer coffee or tea. Fifty randomly selected people were asked, "Do you prefer tea or coffee?" and 25 of them answered coffee. Fifty different randomly selected people were asked, "Do you prefer coffee or tea?" and 20 of them answered coffee. A two-proportion z-test was performed on the data to determine whether the order of the question made a difference. What is the p-value of the test?
