question 17
in order to maximize the chances that experimental groups represent the population of interest, researchers should conduct
____ and ____.

blind group assignment; blind sampling
blind sampling; random group assignment
random sampling; random group assignment
blind group assignment; random sampling

Explanation:

To ensure experimental groups represent the population, random sampling (selecting participants randomly from the population) and random group assignment (randomly assigning selected participants to groups) are key. Blind sampling isn't a standard term; random sampling and random group assignment are the correct methods for generalizability. So the correct option is the one with "random sampling; random group assignment".

Answer:

C. random sampling; random group assignment (assuming the third option is labeled C, with the text "random sampling; random group assignment")
