Question

What am I supposed to do? There isn't anyone in the Science room. So I will just leave this here were a lot of people.

Which of the following supports the use of large, representative samples in a study?

A. The amount of data able to be collected from a small sample may be insufficient.

B. The traits of the sample members may differ randomly from the traits of the population as a whole.

C. Fellow scientists are less likely to believe a study that uses a small sample.

D. The study will be over too soon to gather sufficient data.

Answer 1

the one that supports the use of large, representative samples in a study is :
B. the traits of the sample members may differ randomly from the traits of the population as a whole
Which means that, taking only small number of samples wouldn't be enough to represent the accurate data to find out the cause and effect

hope this helps
