A poll conducted by YouGov for the British newspaper The Daily Telegraph in June 2006 asked a random sample of 1962 British adults several questions about their image of the U.S. One question asked, "How would you rate George W. Bush as a world leader?" The possible choices were (great leader, reasonably satisfactory leader, pretty poor leader, terrible leader).

(a) Is this four-category variable nominal, or ordinal? Why?

(b) Is this variable continuous, or discrete? Why?

(c) Of the 93% of the sample who responded, the percentages in the four categories were 1% (great leader), 16%, 37%, 46% (terrible leader). Arc these values statistics, or parameters? Why?
