_________ are appropriate when there is a single measurement of each element in the sample, or there are several measurements of each element but each variable is analyzed in isolation.
_________ are statistical techniques that attempt to group data based on underlying similarity, and thus allow for interpretation of the data structures. No distinction is made as to which variables are dependent and which are independent.
