    It can't be that... i mean by guessing, people would get it wrong 90% of the times... or are we allowed more structures than the ms? I don't think so though as ER for these questions most of the times states that a lot of people found it difficult.

    Not sure to be honest. I can see one mark for writing about quadrats, that too if you wrote of "equal sizes". It really depends on how you explained it. If you said to compare high land with low land, then maybe more marks...

    now you are scaring me:eek: i wrote random sampling on each type of land.. High and low. and then compare. i wrote random as it was not a gradual increase from low to high. in which case we would use systematic sampling. It was either high OR low. No in between.
