Thank you So much Sir! You’ve helped clear a very disturbing ambiguity in my mind. Thank you so very much.
I did watch the lecture on sources of data Sir. That’s under chapter 2 of the free lectures course. You give examples of stratified sampling based on gender and the systematic sample about asking every 100th person.
I do understand the difference between the two sir, all thanks to you and how brilliantly you’ve explained it. I do however find this particular question to be very misleading as it talks about selecting every 10th person from a hospital ward, randomly. I do understand that they have grouped the people under various hospital wards, that does lead one to think its stratified sampling but when they add the element of picking every 10th person, that adds a possibility of it being systematic sampling no?
Which then led me in further confusion about groupings done in the alphabetical order on people, the second statement, and they too are selected 1 in 10.
Its mind boggling to a point where I cant seem to determine what the fine line is that separates one type from the other in this particular scenario?
I hope I did not lead towards the impression that I’m asking you without having gone through your lectures Sir. My apologies if I did, I would’nt do that. 🙂
Thank you so much Sir! You’re honestly such a great help. I really appreciate your advice sir, I was only going through the study text to be thorough with my preparations. This course really is more than enough. Just had a vague answer in the Study text and hence decided to clear it up. Many Thanks Sir!
