When you draw a multi-phase sample . Group of answer choices

1.You draw two samples and one becomes your control group
2.You use information from a first sample for collecting a subsequent subsample for further study
3.You draw two samples from two separate sample frames
4.you draw a non-probability sample
5.None of the above

The correct answer is letter "B": You use information from a first sample for collecting a subsequent subsample for further study.

Explanation:

Multi-phase sampling is a strategy by which a large number of data under study is taken, then a subsample of that pool is taken, and after that, another smaller subsample is taken in an attempt to count with samples that best might represent the whole population. Usually, the process takes collecting two different samples, but it can be applied as many times as necessary.

step-by-step explanation:

5×5×5+2(8)÷2(2)+3(3)

15+16÷4+9

31÷13

do 31÷13 and u will get ur answer
