The task described is an example of best-worst scaling, where respondents are asked to choose the best and worst options from a subset of items. Block-rank scaling involves ranking a set of items in order, comparative sum scaling involves assigning values to attributes based on their importance, and constant sum scaling involves allocating a fixed number of points across attributes based on their perceived value.
