Answer:

Random assignment to groups.

Explanation:

When conducting an experiment meant to compare a particular factor between two groups of individuals, random assignment to groups is a technique to randomize the subjects. In this case, every individual from both groups is from a particular background and would not help her experiment. What would be ideal and random is to pick up several boys and girls from the same college and compare them, thus, adding the random assignments to the groups.

What connection does the author draw between pericles and democracy in athens?
cestrela7 [59]

Answer: Pericles formed an embryo that would be the prototype of modern democracy centuries later.

Explanation:

  • And if Pericles was the first to devise a political platform reminiscent of democracy in Athens, the Greeks were not the first to use this policy system, but they are the first in Europe. Pericles is known in the historical literature for being an excellent speaker, politician and military leader. He is also credited with the credit for implementing democratic values ​​in ancient Greece and Athens. Around 461 BCE, the period of the establishment of Athenian democracy was due to this man. And if the Athenian pattern of democracy is far from the principle of modern equality, there are certain similarities.
  • Namely, Pericles allowed more impoverished citizens of Athens to participate in the political and judicial life of that city. Thus, the connection between the hereditary relationships based on which the previously mentioned functions was broken is broken. The assembly, in which all the free Athenians were now able to attend, decided on all critical issues. What is sure about the lack of Pericles democracy implemented in Athens is the fact that women and slaves could not participate in these political and judicial processes.
