Answer 1

Answer:

Target Population : All the men & women in the world

Study Population : Men & women in Sarah's college, near her locality, in her city (in US)

Explanation:

Population is the entire set, consisting all members of a group (sharing a common similarity), subject to conducting a research study.

Target Population is the group, to whom a researcher wants to generalise its findings. It denotes whole universe of people selected as the objective research group. It's also called Theoretical population.

Study Population is the group that is accessible by researcher, for carrying out the study. It denotes actual sampling frame, from which researcher draws the sample. It's  also called Accessible Population.

Sample is a smaller subset of population group, drawn to conduct a research study & find inferences about population.

A study about differences in the levels of emotion of jealousy between men and women :

• All the men & women in the world are target population of this research study, as it draws findings about all men & women.
• Men & women in Sarah's college, near her locality, in her city (in US) is study population ; as these are the population accessible by her
• Sample is the 400 college graduates she has examined.
