  1. Thank you very much for the lessons very helpful.
    I am still not quite clear the difference between Stratified and Multistage sampling, as in both you need to divide or split in group. However, it looks to me that if the question mention the word “proportion” or “percentage” it will be definitely Stratified. Am I correct?
    Thank you in advance for your help.

    • As the professor said in the lesson that Stratified sampling focuses on category while Multistage sampling focuses more on groups. e.g. Man or Woman(it’s a category); a big group divided into small groups (it’s not specifically concerning about men or women, they can both in those groups)
      and..yes, “proportion” and “percentage” can be a distinction between these two sampling methods.

  2. it is really helpful. i m gonna sit for the exam on 17th.last time i could not pass as i only read the study book n tried the practice kit may b.only yesterday i found ur opentution website.n now i m able to understand many things which i did assume first time.i m happy to have this lectures. is there any suggestion for me to pass in the exam as i hv very little time.

    • If it is Kaplan then certainly it is OK 馃檪

      But most important is the Exam Kit. If you watch and understand our free lectures then you do not need the Study Text so much.
      However what you do need is lots of practice – the Exam Kit contains lots of exam-standard questions to practice on.

  6. Is there any way to increase the speed of the videos? If not it would be a great feature to add that way people can watch at what they feel is a comfortable speed.

  12. I must admit that this is really a silly question (and I will remove it from the notes).
    There are arguments regarding all of the choices – I will not go into them because it will only cause confusion and waste your time.
    Sorry 馃檨

    • Primary or secondary depends on why the data was collected (not who is using it).

      So, with the census various information is published. For example, it might give the proportions of the population within different age groups. Because the data was collected specifically to give this information (by there being a question on the census form) it is primary.
      Secondary is when the data was collected for some other reason and then used for a different reason.

      • So, there is nothing related to internal and external source of data. I think this point makes the question 1 confusing to us. Also thank you for your lecture!

    • Primary data in simple terms is unused or processed data
      whereas secondary data been data already used for a different purpose which you are not going to rely on for on to perform a task

  19. No – the answer is C.

    The question is a little silly to be honest, but the reason is that (i) and (iii) are calculated using data that was collected for another purpose.
    (ii) and (iv) we are using data that exists specifically for a purpose.
