For each of the following research situations, identify the level of measurement of all variables. Also, decide which statistical applications are used: descriptive statistics (single variable), descriptive statistics (two or more variables), or inferential statistics. Remember that it is quite common for a given situation to require more than one type of application. The administration of your university is proposing a change in parking policy. You select a random sample of students and ask each one if he or she favors or opposes the change. You then use the results to estimate the support for the change in the entire student body. You ask everyone in your social research class for their highest grade in any math course and the grade on a recent statistics test. You compare the two sets of scores to see if there is any relationship. Your aunt is running for mayor and hires you to question a sample of voters about their concerns.
