The nation dataset contains similarity ratings between twelve nations, as collected by Wish (1971).
In 1968, Wish asked 18 students in his psychological measurement class to rate the perceived similarity between each pair of twelve nations using a 9-point scale,
where '1' indicates "very different" and '9' indicates "very similar". The data in this dataset represent the average similarity ratings between these nations.
