Suppose you recruit the next 100 people who visit the DCC cafeteria to participate in a survey. One of the questions you ask is whether the student eats on campus (i.e., in the cafeteria) regularly, and you want to use the sample proportion to estimate the value of the (population) proportion of all DCC students who eat on campus regularly. Do you think this sampling method is likely to be biased? If so, in which direction? This sampling method is not likely to be biased and will produce a representative sample of DCC students. This sampling method is biased and is likely to yield an overestimate for the population proportion. This sampling method is biased and is likely to yield an underestimate for the population proportion.

A researcher wants to survey 2000 Americans for an obesity study. Match the strategies to their corresponding sampling techniques. The researcher posts the survey on the Internet the survey question and waits until 2000 people have responded. The researcher picks 20 different small groups:a church group a Democrat club a student club etc. each containing 100 people. Then the researcher makes sure that everyone from each group answers the survey question. The researcher gets the complete list from the Census Bureau and surveys every 1500th person on the list. The researcher makes sure that the proportion of respondents from each state matches the proportion of each state's population to the US population. The researcher gets the complete list from the Census Bureau and uses a computer to randomly select 2000 people.
