Answer 1

The correct option is (a) Breaking down a whole group into smaller sub groups

The best I can explain: Stratification of information is one of the statistical tools which means breaking down of the whole group into smaller sub-groups. Run charts, effect diagram, pareto diagram and scatter diagrams are also the statistical tools.
