Answer 5

Ben, if you're not sure, it's better that you either stay on the sidelines or at least show your own work. Otherwise valuable time is lost. Thank you.

Answer 6

Howard, I think your best bet ate this point is to look up all four answer choices on the 'Net and look for examples. The benefit of your doing this would be (1) a quick review of the meaning, with examples, of the different types of sampling, and (2) examples of same.

Answer 7

ok I will, but does this mean im incorrect on one or more of them

Answer 8

Please see the following search results for "cluster sampling." Note how there are definitions as well as examples. No, I am not implying either that your answer choices are correct or that they are not.

Answer 9

hmm, ok give me a moment to search here

Answer 10

Sure. I appreciate your willingness to invest your own time and to follow at least some of my suggestions.

Answer 12

This is a well-written, comprehensive source, and I commend you for having found it. With the examples it gives as references, you should now be better able to decide what typsw of sampling are represented in the problems you've posted.
