Answer:
This sampling method is called cluster sampling.
Explanation:
In cluster sampling, the researcher will first divide the population into separate groups. The researcher in the passage focused on sixth graders of a certain state as his subjects. The next step is to select a simple random sample of clusters from that population. In this case, the researcher randomly selected 5% of the districts in the state, and administered the achievement test to their sixth graders. Therefore, we can safely say he used cluster sampling.

Answer:the use of formal operational thought
Explanation:The formal operational stage is the fourth and final stage of Jean Piaget's theory of cognitive development. It begins at approximately age 12 and lasts into adulthood. At this point in development, thinking becomes much more sophisticated and advanced.
Additionally, while younger children solve problems through trial and error, adolescents demonstrate hypothetical-deductive reasoning, which is developing hypotheses based on what might logically occur. They are able to think about all the possibilities in a situation beforehand, and then test them systematically (Crain, 2005). Now they are able to engage in true scientific thinking.
