Their thinking needs to be challenged. Is there (or can there be) a general algorithm to solve Rubik's cubes of any dimension? e.g. Median of {1,2,3,1000000} is (2+3)/2 = 2.5. Medians and categorical data Even though the median may be carefully defined as the middle value in an ordered data set, students sometimes try to find the median of categorical data sets.
