Use the guidelines to evaluate the study. Discuss flaws that you see in the study. A researcher randomly selects 300 adults from the city of Kentwood by using a random number generator and a list of residents of the town. She calls the people in the sample and asks the following question: "Do you agree that more of the city's budget should be spent on social services for the poor? " She announces that 54% of the people in Kentwood feel that more of the city's budget should be spent on social services for the poor.
What will be an ideal response?
Limited choice is given in the question. There is not enough information to answer the question - what other choices are there? If more is spent on social services, will cuts be made elsewhere? It is impossible to decide on one piece of the budget without seeing the whole picture and knowing all the alternatives.
