Respuesta :

i think the answer is population.

Let's say the study group is men between age of 16 - 20. Then example of  the population of that group would be all men in all age groups

hope this helps
I believe the correct answer to fill in would be the term population. The larger pool of subjects from which a study group is chosen is called the population. It refers to the entire pool of possible subjects. Hope this answers the question. Have a nice day.
