You have been given access to a group of 12 jurors, with a mandate from your senior researcher to “go and find out about their prior jury experience.” Under each of the following three sets of restrictions, devise a question to ask the jurors about the number of experiences they have had with previous juries
a. The information may be recorded only on a nominal scale of measurement. b. The information may be recorded on an ordinal scale but not on any higher scale of measurement. c. The information may be recorded on an interval scale. Your senior researcher subsequently informs you that she wishes to know the answers to the following five questions: —How many of the jurors have served on a jury before? —Who is the juror with the most prior experience? —What is the sum total of previous jury experience? —Is there anyone on the jury who has served more than three times? —What is the average amount of prior jury experience for this group? d. If you had collected data at the nominal level, which (if any) of the above questions would you be in a position to answer? e. If you had collected data at the ordinal level, which (if any) of the above questions would you be in a position to answer? f. If you had collected data at the interval level, which (if any) of the above questions would you be in a position to answer?
