Question

As a clinical trials monitor, you recruit subjects for a new study. You want 175 subjects per group for 3 groups. How many subjects should you recruit for the whole study?

Answer 1

To find the answer, we can use multiplication, by multiplying the subjects needed for each group by the total number for the whole study:

subjects per group × total number of groups
= 175 × 3
=525

Therefore, 525 subjects is needed for the whole study.

Hope it helps!
