Really sorry for taking so much time to comment on your post.
The topic that was to you assigned was multiphase sampling. It’s very good that you have pointed out the difference between multi stage sampling and multiphase sampling. In your post you have mentioned the following statement:
Multi-phase sampling is useful when the frame lacks auxiliary information that could be used to stratify the population or to screen out part of the population.
Could you please explain the term auxiliary information with an example? And how can multiphase sampling help in lack of it? I would also like to know how the pictures that you uploaded are related with multiphase sampling, or rather did you have anything specific in mind while uploading these pictures. Also, could each one of you give me a different example of a multiphase sample? Cya till then.. I know you all have lot of work to do but I’d appreciate it if you could answer my questions ASAP.
