To accurately represent the target population, a small sample should be randomly selected. representative of the whole group. representative in terms of demographic traits (age, region, religion, race, and the like). representative in terms of opinions. all of the above are true.

The correct answer is: all of the above are true.

In order for a psychological study's findings to accurately represent the target population, the study's sample needs to be chosen accordingly. To elaborate, the sample should be:

i) Randomly chosen- this avoids any bias and leads to a more diverse sample from the target population

ii)Representative of the whole group- so that individuals from the target group are not excluded

iii) Representative in terms of demographic traits (age, region, religion, race, and the like)- so that all subgroups, races, religions, age, etc., from the target population are represented

iv) Representative in terms of opinions- Even within a target group, members have varying opinions. Random sampling ensures that various opinions are represented.
