Level of Measurement?Which of the levels of measurement (nominal, ordinal, interval, ratio) describe data that cannot be used with the methods of rank correlation? Explain.
Solution 2BSC Step 1 Now as ordinal, interval or ratio data are in the form of ranks or if not it can be converted to ranks, hence rank correlation can be used in these given, even the data cannot be converted into ranks being nominal.Rank correlation can be used for the data which are in the form of ranks or can be converted to ranks. So in case of nominal data rank correlation cannot be used. (In nominal measurement the numerical values just "name" the attribute uniquely. In ordinal measurement the attributes can be rank-ordered,In interval measurement the distance between attributes does have meaning.and in ratio measurement there is always an absolute zero)
