danlan In stratified random sample, items are groups to represent each group of interest, so each item may have different probability of being sampled.
Jurrens to expand on danlan:
Every group may have different number of members, ie, one group has 5 and the other has 2. If one member from each group is chosen, the group with 2 has a much beeter chance of being selected.
renataa Thanks Jurrens, very helpful
