Buster runs an experiment in which she finds that participants placed in a good mood by a happy film clip are more likely to offer to a fellow participant than participants who see a sad film clip. gob suggests that perhaps this difference simply results from the fact that the participants in the happy film clip condition were more people to begin with. what methodological aspect of a successful experiment can buster point to in order to refute this criticism?

In psychological studies, random assignment refers to the use of procedures that guarantee that each participant has the same probability of assignment or choice in the study groups.

It is necessary to take into account that random assignment and random selection are different, since the first refers to the distribution of participants in random and balanced ways in experimental groups and the second refers to the selection of individuals capable of representing certain characteristics of a population

Answer

The experimental methodological aspect that Buster can point out to refute that criticism is the random assignment, whereby study participants are randomly assigned to different groups.

panem is a communist totalitarian dictatorship where all the resources and how they are allocated belongs to the capitol. the districts exist only to provide goods and services for the capital and most of the citizens live in poverty. it is a police state where the "peacekeepers" use force and threats to keep the people under control. dissent is outlawed and those who disobey the law are executed, flogged, or turned into avoxes. the games are another means in which the ruling elite in the capitol exert their power over the districts. when reading the books i drew parallels between panem and the soviet union and north korea. in no way is panem capitalist. the people in the capitol are wealthy but the majority of them are involved in the government somehow. it was the same way in the former soviet union where bigwigs in the communist party and high ranking government officials were given access to goods, services, medical treatments not available to the general public. if you think panem has a capitalist economy you need to brush up on your economics.
