Aren't stratified and systematic sampling strategies, in fact, designed to
be _more_ assured of "representative-ness" than simple random sampling? The
stratification or system selection introduce elements of non-randomness, but
the choice within each stratum and the starting point for systematic
collection still retains the essential element of randomness.
