For your marketing class, you'd like to take a survey from a sample of all the Catholic Church members in your city to assess the market for a DVD about Pope Francis's first year as pope. A list of churches shows 17 Catholic churches within the city limits. Rather than try to obtain a list of all members of all these churches, you decide to pick 3 churches at random For those churches, you'll ask to get a list of all current members and contact 100 members at random a) What kind of design have you used? b) What could go wrong with the design that you have proposed? a a) Choose the correct answer below O A. This is a multistage design, with a cluster sample at the first stage and a simple random sample for each cluster. OB. This is a multistage design, with a cluster sample at the first stage and a systematic sample for each cluster. OC. This is a multistage design, with a convenience sample at the first stage and a simple random sample for each cluster OD. This is a stratified random sample b) Choose the correct answer below. OA. It will produce a voluntary response bias as it will only include the three churches that opt in OB. It will produce undercoverage bias because three churches are not enough OC. It will produce a nonresponse bias because many of the members will not be called OD. If any of the three churches are not representative then that church introduces bias to the whole sample OE. There can be no bias in this method of sampling
